All I needed was to figure out how to install packages on vsc since I only ever used pycharm for months and this was the first video that actually showed me that you have to tap in to "py -m" first, no other videos showed that, so thank you

This is great ! Thanks ! For the weather example - I also added a "raise" exception" (following your exception tutorial) in case a city is not found ( weather_data["cod"] == "404")

perfect tutorial, you really saved me today. The confusion from today's class is gone.

@ahmad-murery Жыл бұрын

You may want to add pip directory to the *Path* system environment variable, this way you can call it directly without adding *py -m* in front of it. I prefer using the *source* command unless I'm in a bad mood I'll use the dot (.) as a shortcut Thanks Dave!

Appreciate. The official Python recommendation is pipenv. I'm also looking forward to the Pipenv lesson.

@DaveGrayTeachesCode Жыл бұрын

Thanks - it seems venv used to be and pipenv just got the recommendation in 2022. I won't double up on these in this series, but maybe another look in the future. The overall concept and goal works with either.

Hi Dave! This was very helpful. I am a Python beginner and I find that you explain things that a lot of instructors forget (the curse of knowledge). I do have a question though. As you were typing in the function it showed it created a test. Can you tell me what extension you are using? And do you have any suggestions on extensions?

@xzex2609 10 ай бұрын

thank you for your Great work , I think one thing was not clarified at the end and we creates some .gitignore and .env files to protect our API KEY but in the end I didn't understand the next step is just commit the project to git hub ? or there is more to it ? I appreciate if some one help me understand it.

Damn that's so good! Thank you so much for your time and teaching style! A+ On the virtual environments, if the .py file is stored/run from a different environment (or anyplace else), is there a way at the top of the script to force it to use the python.exe and dependencies in THIS one-- the one (virtual environment) that we just created? That is something about virtual environments that I am not clear on yet. Thank you!

What am I doing wrong? Any help greatly appreciated. from dotenv import load_dotenv Import "dotenv" could not be resolved Pylance I've followed the steps of setting up the virtual environment, I can see in the requirements.txt python-dotenv=1.0.0. I'm using python 3.11.1. This also happens on lesson 23 with dotenv and flask.

I have a solution for you guys: 1. Hit ctrl + p in vscode. 2. Type: >Python: select interpreter and select it 3. Click "Enter interpreter path..." 4. Enter the path or click "Find" and browse to the path to ".venv/Scripts/python.exe" (select python.exe) 5. check that this python.exe is now your selected interpreter, it should now work.

I got the exactly same error. I saw someone on StackOverFlow saying that source only makes sense in Linux, so you can only use source in bash terminal. But bash terminal throws a "No such file or directory" error.
