Your shirt confused me more than python

“If you’re about to install Python for the first time, you’re almost certainly, gonna do it wrong.” This man understand me.

Me: watching how to install python Python Programmer: let's play the ukulele

Thank you so much for sharing this. I've been developing command line, desktop and web software over years on Linux and Windows, and have been thinking about which machine learning/ IoT project to launch into next, but have paused this development knowing python and library versioning issues could create more grief than I'm ready to deal with. Your tutorial on virtual python environments may be a game changer for me, as now I can continue development without these roadblocks derailing my efforts!

FINNALLY!! not just another super technical "introduction" striped of high level illustration of what the topic is about. thank you for keeping it dumbed down for a set amount of time before introducing abbreviations after abbreviations

Virtual environments are, indeed, important to use when you're doing Python development. But, they are not part of "installing python" - they're part of using python. This strikes me as clickbait.

The ukelele tutorial really helped with my ADHD, this is probably the first time in my KZfaq history I watched a KZfaq video without tuning out and rewinding. Please consider keeping it if you haven't already. Thanks

Learned it the hard way. Cloud based solutions are also good for this. Anaconda offer the possibility of setting up multiple environments as well.

Incredible how you combine Maxwell's equations, playing a ukelele during installing python!

The bit with the ukulele cracked me up. Maybe I should too bring my piano up whenever I install something X'D

Taking your Python course in Udemy is a good decision I made toward learning data science. Thank you for sharing your passion to teach and inspiring people like myself to learn computational thinking and Python.

Do you save your project files corresponding to 'my_env' in 'pyproj\my_env', 'pyproj' or 'pyproj\my_env\Scripts'?

I thought you were going to talk about Anaconda but still was a great video, I didn't know you could create venvs without modules or conda.

The title is a bit misleading. You nailed some early frustrations when first learning Python that are not clear coming from using other package managers. I should note that virtual environments are great from a development perspective, but moving that to a deployable for systems on a network without going through pypi is still not well explained or documented, and to be frank shouldn't need to be. What I'd prefer is a simple command and clear standard to package the venv completely with the deps in it as the installable package. I think wheels is trying to fill this hole, but it still feels way more esoteric than it needs to be if not following the "put it on pypi" norm you see on tons of tutorials.

Heyyy Love from India 🇮🇳 If you happen to come to India or need a break from your routine, I will be glad to host you.

Came here for ukelele lessons and now I'm a software engineer somehow

Wait. I'm really interested in knowing why are Maxwell's Equations on the board.

OH MY GOD!!! I WAS JUST INSTALLING PYTHON AND YOU HAVE BLESSED ME!!!

Use miniconda , simple yet effective . Learned it hard way when most deep learning models don't have compatibility with tensorflow 2+

This may be obvious to most, but can you comment on this virtual environment and where you would store your actual python code files. Would it be in this "pyproj" folder or a subfolder. Would you just add git to this folder that has the python code files? And last can you talk about how you would update python to the next version with this approach? Thanks so much great video.

I don't quite get it. What if I do want to use Visual Studio now? Do I connect somehow the pyver or pyproj folder to vsc? Or if I want to use vsc then should I just ignore this tutorial?

In your course - do you give directions / advise on setup from the complete beginner? It would be even better if you explain how to do this with MS Visual Studio IDE

Thank you so much for the video. I had such conflicts you mention. I was told to use anaconda instead, to manage the packages. Do you think your method is best than using anaconda? What would be the advantages/disadvantages of your method above anaconda? Thank you in advance

Ooooh, love the whiteboard with Maxwells equations in the background :)

If pip and or python aren't recognized in spite of re-installing Python over and over, try this.. Move the path variables for those up to the top of the path list. For me, there was a bad path somewhere in an old path setting that was being found first before my new path entry was found and thus the new path setting was ignored. Using the Move Up button, I moved my new path settings for Python and Python\Scripts up to the top of the list and problem solved!

Glad you are back. ❤️❤️

Thought this would be about managing multiple versions of Python in an OS (e.g. pyenv) It seemed like you want to have a completely separate installation of Python for every project to be made, potentially installing the same version several times for each project. Isn't that kind of... janky?

Thx for the video, i did end having the issues you mention running different projects. This time i'm resetting everything and doing the right way. but i still have some questions, i was planning to install 4 different version none of them without global path set, - but it is recommended to install one with a global python? (not sure if any program is going to try to install anything in base python, i think chocolatey do but not sure?) - should i keep one with global variable so any programs that requires python to be accessed in the terminal without having to declare and activate my venv. - can i create a venv and turn this venv into my global variable, using the python in my venv\Scripts? - witch python do you recommended as the base global if needed? (i have end using this versions in my projects i have use 3.10.6 , 3.9.13 , and 3.11.3) - If a program runs in example 3.10.6 (should it work in all 3.10.x version?), are the 3rdnumber just for small updates or are this breaking points for projects and combabilities stays? i'm asking because this time i might install the latest version of each 3.9.x - 3.10.x - 3.11.x. Thanks in advance.

How did I not find you yet? I am a subscriber now, and also a fan of your videos. Thanks!

This was definitely one of the pieces of the puzzle that I've been missing! Thank you so much!

i wish i could try what you're doing there myself but my ukulele is not even tuned correctly atm

good strategy with the ukelele for "wait times", I usually check something on the web and then forget to ever come back. An instrument provides a diversion with a limited amount of options. I'll run out of chords/song fairly quickly and then remember to get back to work.

Thanks for this, can you still keep running in the virtual environment when it goes live or is it just for testing?

this was immeasurably helpful. other creators glaze over all of the finer details of setting up python and I wasnt even able to install libraries, and now i can. thank you so much for this video!

omg you are 100% spot on with the dependency issues that surface !

Some Maxwell’s equations in the background, cool :) Cheers!

Danger! Warniing! Danger! Warning! This video includes a maniac playing his ukulele. Enter at your own risk. Switching off your computer provides temporary protection. Reboot at your own risk.

Where is the best place to learn Maxwell's equations?

'i am getting this tree' is not recognized as an internal or external command, operable program or batch file.

Welcome back-- missed the videos

Got a question, I don't remember how I installed it last time since it was a year ago but I probably made similar mistakes that you did, I didn't set it up on my vscode either, then when I had a python file there and wanted to run coverage or similar tests, I got a wrong command error as it likely was the python problem since I had it in 3 different folders somehow. I have uninstalled it and removed from PATH including my IDEs that use it, now I wanted to reinstall it, should I do it your way then just install vscode again, somehow set it up, will it work like that or should I just default install and tick the add to path option?

Hi Newbie here! I keep getting this error whenever I try to create a path to my_env folder 'c:\Users\Name' is not recognized as an internal or external command, operable program or batch file. Can anyone please tell me how to fix this? Would really help a lot thank you!

Thank you I really appreciate you providing that tip to help version control. You walked thru things and they made perfect sense and simple to do. Greatly appreciate it.

If you use a code editor instead of the command prompt do you still need to use virtual environments?

Thank you, very clarifying explanation on Python's virtual environments. The ukelele is great but I prefer the guitar. Maxwell's equations are also great but Einstein's General Relativity equations are more appealing ;-) (I don't mention Schrödinger equation because, in spite of its practical success, it is "probably" wrong :-D)

When I followed these steps in the video and run the "python -- " command on VS code terminal, it says python is not found but on doing the same thing on windows cmd , it is showing the python version . Any idea why is that?

OMG! This is sooooo helpful! I have experienced the conflict issues in the past working on my own projects when first learning. Thank you!

if you wanna get even more advanced, try using pyenv and poetry for managing python versions and packages, it's comfy

This was amazingly helpful. Love your sense of humor as well. Thanks so much.

Hello Giles, thank you so much for this video. What an amazing video! I've never saw it anywhere else.

yayy you're back!! Thank you for the video. Looking forward to more to come! :)

This literally happened to me, so glad I saw this

Thanks this is a very informative video but im still having trouble. for some reason im guessing this error while trying to activate 'my_env\Scripts\activate' is not recognized as an internal or external command, operable program or batch file. i also had a error when making virtual enviroment, but when i typed in 'dir' command, i could see the envitoment i made in there any help would be amazing, I have been having alot of problems with this thanks

Great video, thanks! Now, if I want to use poetry to create python packages, I'd probably want to install poetry "globally". When I have multiple python versions installed (and maybe for each python version several virtual environments set up), would I need to install poetry for each python version individually (by typing e.g. C:\python-vers\py3124\Scripts\pip.exe install poetry)? Actually I tried this command but just could not find my poetry installation and how to use it... typing "poetry init" resulted in a command not found error.

Thank You. 👍🙏. I’m glad that this is now installed on my computer before I start making projects. I still have difficulty understanding VE, but it will take me some time to learn it

Great video. Is using environments in MS Visual Studio the same as creating virtual environments?

Virtualisation is cool however th Colab from Google is also perfect alternative to install completely nothing on PC

Just found your channel and Im delighted. Older coder here not too excited by the newest languages but came across all the uses for Python and had a look here first. I'm grateful you did these videos. Thanks so very much!

Great stuff Giles, I like your whacky style - and also Maxwell's equations!

Is this still possible to do these steps even though I have already downloaded Python?

My Gods, I could listen to you talk about anything! Especially if there's gonna be a ukulele break!

Hi, Giles, I am a python begnner and thanks a lot for your great advice. I've seen many of your videos about best python books you recommended and I've bought some of them including and etc.. Your playing piano and ukulele is very cool , and I love music as well even I hope to learn some music analysis ,composing, gaming by machine learning in the future if possible . Have you ever set up some projects about music?

Thanks Giles :-) Been coding python for over a year now for several projects, some application based, some POC projects. Wish I knew this before I started, would save a lot of package bloat. However just have a new PC so decided to set it up this way - brilliant:-)

Great stuff! Thanks. But how do we keep track of the many virtualenvs and the packages in each one of them?

Really regret discovering your channel so late. Absolutely love the pace at which you speak and the interludes. Nonetheless coming here to sharpen my python skills.

I'm still confused about CUDA, Pytorch and other stuff that is a mess... When you start using virtual environments.

That was fantastic, thank you. Just what I was looking for.

HI everyone, I would like to check that when I typed my path at 8:10, there was an error showing "No module named my_env". May I know how to fix this issue? I googled it but Im still confused with the explanation.

Thanks for this video, still in the middle of watching it but I wanted to say that in case I forget which I usually do. I've been dabbling with python for months now and I would have to say this is probably one of the biggest lapses in my self Learning Journey.

Very nice ! mi amigo, this tips it's very great, and the mixing ukulele, that wonderful, thanks for your time.

Wondering at 04:30 what about installing it on an (entirely) new pc, installing python for the first time. Do I still skip ticking to add it to PATH??

That was awesome I try all and now I can call pip with out an error in the CMD prompt. Now if you would be so kind and show how to download 2to3 to that path you make and I, It would be much appreciate. Thanks and keep them tuts coming.

Isn't installing anaconda better vs setting it straight on windows ?

It would be great if you could make a version for the Mac...

Makes sense, never got that far with projects, totally watching later, thanks mate! :)

Great video and I learned something today! Trying to figure out how I can implement at work with dozens of Python scripts running on a remote desktop (or laptop) - we'd need the virtual environments setup on THAT machine, no? Windows machine runs all the scripts via Task Scheduler

Thank you so much. You really helped me a lot. I too am a physicist so i can appreciate maxwells equations. Liked and subscribed👍🏽

When you talk about virtual environments are they the same thing as virtual machines such as Oracle's virtul box, VMWare virtual machine and windows hyperV?

Thanks for this. The ukulele segment was exceptional lol

Hi, how do I activate the created virtual environment in Visual Studio Code? my_env\Scripts\activate did not work in VSC's Terminal.

excellent video! What do you recommend when a newer version comes out? current version is 3.10.4 so you install it in c:\users\giles\pyver\py3104. When 3.10.5 arrives do you install it into c:\users\giles\pyver\py3105 and de-install 3.10.4 or let it be?

"those two chords in the ukulele go well together... So, let's see if it's installed now". Pretty funny.

Thanks for your help; question: How can I direct any Python output to my printer in windows 10? I have an EPSON WF-3620 Series printer. Thanks very much already.

VIDEO SUMUP for those who need (please watch the video before, it is quality and fun, thanks Giles McMullen): Installing Python and developing projects using virtual environment: - 1 virtual environment for 1 project -> avoid dependencies incompatibilities between projects thanks to a "sandbox" - you can share this environement with colleague with who you collaborate STEPS TO FOLLOW: Python version installation: - create a folder for you python installations (name example: pyver) - when installing a new python version, don't add the python exe to the PATH and think to install it in the folder mentioned previously (customized install) Virtual environment creation for a project (for Windows): - create a folder for you python projects (name example: pyproj) - open a command prompt and move into it (eg: using cd command -> cd pyproj) - create the virtual environment thanks to a Python option with the following command: \your\python\path\python -m venv my_env (adapt \your\python\path\python with the path of the Python interpreter you want to use, and replace my_env by the name you want for your environment) - now you should have a my_env folder in pyproj Virtual environment activation (we are still in the pyproj folder): - launch the command my_env\Scripts\activate - the my_env environement should now be activated and mentioned at the beginning of your command prompt - if you launch the python command you can check that the python version launched is the same as the one of the interpreter used previously - if you try to import a lib it won't work because no lib has been installed in your environment yet Installing a libraty in a virtual environment: - as usual as outside an environment, use pip: pip install lib_name - you can now import the lib installed in your environment Virtual environment deactivation: - use deactivate command

Great video, thanks. It would be a great help if you could do a followup video on how to package and deploy to production server once Python project is done.

I think it’s comparable to the difference between a DAW (digital audio workstation; abelton, logic, etc) and a plug-in (samplers, FX, synths) for music production.

This is a great introduction for people who are just getting into python, but don't don't want to step into the world of Anaconda etc, which seems to add more complexity. Speaking from experience. Thanks!

Thank you for demystifying this subject. What a relief!

Tnx much for the instrunctions. Do we have to go trough all the process again every time starting a new project or is there a short version? I am thinking Project 1 and 2 and so on.... tnx very much

Not sure why you're recommending venv when virtualenv (a) boots faster, (b) offers support for Python 2 (if you're stuck having to support that), and (c) most importantly, allows you to cross Python versions (e.g., while running Python 3.11.4 for example, you can `virtualenv -p python3.9` to create a virtual environment running under Python 3.9).

Awesome - just signed up for the Udemy course !

....think about you have to work on system provided by your employer, software packages were created to be installed by push portal, all setup settings preset, and you do not have any admin rights at all....

If I've never downloaded Python before should I add it to the PATH? In another one of your videos you're quite "pro" adding it. If I do, should a directory be made like the rest of the tutorial? Sorry I'm just a bit confused... I literally have 0 idea as to what I'm doing

Such a practical and logical install, as it should be done mate, thanks a lot, this will help me a lot with the famous python interpreters

VENV hopefully doesn't require virtualization enabled because that's only available in windows 10 pro not home. Also at 3:15 you say "once you're done , launch the set up application " . Say what ? Do I type a particular key ? Mumble "launch" to Cortana ? How is this "launch" process activated ?

thanks a lot, I've followed this guide to install python, hope everything works for the better.

Good video. Have you considered a video on using Docker for managing Python development environment versioning?

This is great advice.. Best to get into the habit from the beginning.. Also makes it super easy to deploy to heroku and so on as you can freeze the requirements to a text file

Finally, a new video after a long time. I wish you had brought out this video when I was installing Python but batter late than never. By the way, nice design on shirt :-)
