OH GOD me and my friend were looking a perfect tutorial for this like last week and you released these!!! You'll probably go down as the most loved programmer!!

I've been waiting for this.....Great Tutorial and Awesome Video!

you literally have a video for everything. I LOVE IT

The moment when you are sure that you have seen all of his mugs... It is an illusion

You are the number one of python programmers, thanks for sharing.

Just for info. If anybody has any difficulty in understanding the code in the video, head over to the text version of the tutorial. It has been explained beautifully. Thanks Harrison :-)

I've seen a lot of tutorial videos of many people on many things but your way of explanation is the best! It's clear and simple, I love it.

Hell yeah..! Really great tutorial. Exactly what I needed. Wish you good fortune :-)

I haven’t done this but I am very sure if I do, it’s gonna work ! This is so amazing! It has everything I want, I want to say a very big thank you 🙏🙂 keep it up bro

you're a legend thank you so much this is helps me in my project

always love your incredible tea cups)))

for handling client inputs and printing other inputs of other clients at the same time for this, you just have to make input non-blocking. this may help I guess. r_list , _,exe_list = select.select([sys.stdin,client_socket],[],[sys.stdin,client_socket]) for read in r_list: if read == client_socket: msg = client_socket.recv() else: out_msg = sys.stdin.readline().decode('utf8') client_socket.send(out_msg) btw by far best tutorial on sockets and one of the best channel on youtube

Thank you! Very interesting experience. You do good tutorials)

Excellent video series! Thank you!

this is awesome..thanks I will use this when getting serious on my Python coding lessons

Great tutorial. Has sent me in the right direction.

great series - many thanks

Best python youtuber hands down

In your written code for the client there is a typo in the last exception: except Exception as e: # Any other exception - something happened, exit print('Reading error: '.format(str(e))) sys.exit() you're formating but there are no {} inside the string. Love that tutorial, was a lot of fun to build that. Have a good one!

Thank you for this tutorial!! ❤️

Hey sentdex buddy ol' pal, are you considering continuing this tutorial? found it super fun and learned a ton. would love to see gui implementation!

great stuff as always man

Could you please explain more about blocking vs non-blocking recv() and how to implement command/response protocols with timeouts?

Awesome tutorial, thanks.

Thanks man for this awesome tutorial!!!! From where do you learn all this stuff? Because you teach everything so perfectly!

It worked! Thank you! :)

thank you, very helpfull , hopefully i could implement it to iot devices soon

Thankyou! You are my inspiration :)

+1 on seeing you do this with Qt5 :)

Would be cool if you did a video expanding on this with regards to the server looking for keywords, and then executing a bit of script from a program you've written. Like !roll sent from a user randoms a d6. Or incorperating a little 'mini game' involving another .py file.

Nice work!

Hey, I have a question, how do you interact with each thread ? for instance, if you want to send data from server to a specific client using whatever thread id or anything else. So if server got 3 clients connected, now you want the server to send data to specific client by using thread id or thread ident number or anything. I tried and failed. Can you guide me ?

Thanks, really helpful

Still you are working with us thank you

"Cool!" Part 2 the revenge of the cold

really great tutorial, I actually took your idea and used a Tkinter GUI for it. I have one question though , if say like I want the server to make a list of all connected clients and broadcast that list so it can be shown in the client GUI and ofcours it would be continuously update.. how can I do that ?

Amazing!

Great Socket tutorial, thanks. It kept me wondering is it possible to run these in Sublime Text?

It says "Reading error [WinError 10035] A non-blocking socket operation could not be completed immediately" and the connection closed immediately from the server.

For those of you interested, I made a GUI version of this using tkinter that also constantly checks for new messages. Here, have a look: github.com/Everton-Colombo/Socket-Chatroom

if i want to make the application public to download, and a private chat(person to person) how do i know which ports are open for use in the clients system, and also i suppose i need to make a server that will connect between two clients, by username. main question is how do i know which ports are ready to use

Great tutorial. Where can find the server and client code scripts written in this tutorial?

I love your videos and actually highly appreciate it if you would teach us (I'm a total python noob just following the steps of the tutorial) how to put this in a GUI.

For the message receiving without input try _thread or if you don’t have it as a module look at threading(I use pythonista and have _thread but pythonista has different things).and try and make the output and input functions because the module runs two functions and tuples of them(if no input use (,)), The module will continuously run both simotaniously, it is not perfect but works good on my projects, try it out with a copy, it may work or completely break the code

nice work

Hey I found a way to attach it into a UI. The biggest "issue" is that I had to break your While True and instead had it look for new messages every 1 second. While there might be some lag (literally up to a second), I find this more than useful to people who would be following these tutorials. Just so you know I simply took your code and modified it to work with a .ui file. Using a .ui with Qt Designer is very user-friendly. If you are interested in what I made let me know.

In case you don't like the weird way to convert with f-strings/strip to manage bytes, here is another version: bytes_header = int.to_bytes(len(bytes_message), HEADER_LENTH, "big") int_header = int.from_bytes(bytes_header, "big") And to convert utf8-string to bytes: bytes_data = bytes(data, "utf-8") utf8_data = bytes_data.decode("utf-8")

Great tutorial! Is the GUI video uploaded yet?

Its a great video...can you tell me how to run python file from the local server to client server? or is there any other ways to run python file?

Help Please! After running the server, I open a client and give my username there. But when I open a second client(and give the username there) and try to send a message from the first client, the following error shows up Traceback (most recent call last): File "client.py", line 44, in client_socket.send(message_header + message) ConnectionResetError: [Errno 104] Connection reset by peer It would be really great if someone could point out where the mistake was!

bro you are amazing

Greate video! Question will this code be able to control the clients pc? like run commands in the command line and such? Thanks!

which ip have you put in the client and server file when you are connecting with other machines on other networks

How can I connect to the server from another computer? I have tried multiple IP’s and received various errors such as “no connect route” and “host error”. Anyway I can connect a remote device to my server?

I am very confused atm. I have followed your exact code, even copy and pasted the code from your website, but I do not seem to get the "new client connection" message. Does anyone have any possible reason for this that there could be?

u actually save me ! that is my project for university but in which video u have worked on UI?

Could someone explain to me what the ":

Nice tutorial, can I send message from server to clients? without block?

How do I make this actually work across multiple computers, so that I can actually talk to other people and not myself

This is great. Could you make a tutorial on how to make a video chat program? Info on the web seems scarce on this point. Also, how do you connect server to clients over the internet?

i know this is an old video but the logic still works, now the question is , if i want to make this public (connection with different network) then how the connection will work

So there is or isn't way to make chat automatically updated when new message is recived?

How is the client code exiting out of the while True: # receive things and not stuck in an infinite loop? Thank you for the tutorial

I totally used/sponged this.

Awasome tutorial

how do i make this work accross multiple computers? i've tried using a hamachi server but it just doesnt connect. even my own ipv4 address doesnt work, it says the ip is not valid in its context. can someone please help?

Can you please write the code into the comment section or the description because I’m really struggling to keep up on everything you are doing thank you:)

Hey, did the vid for creating the GUI part of a chat room get posted on youtube..?

in your text-based tutorial you didn't import sys, might want to fix that

Is there a way that the client can pick who they want to send a message to if there are more than two clients?

I simply love these tutorials. just a couple of things...You said that you wish that you don't have to go to your folder and then initialize client and server by using the CMD...well...just doble click the py files and that's all :) 2. Can you please do an example by using an EXTERNAL server like a server in dreamhost or any other provider? that would be GREAT since there are SSL issues that I would like to see how you handle them. Thanks for your time and amazing work.

I know this is an old video, but I've been trying to host a game I've been working online to play with a friend. I have managed to get the sockets to work on my local internet but I can't find any explanation on how to do it online.

will your program work if the client and server programs are running from different devices?

on the website you forgot to import sys. also, unused import statement select on client

When i send more than two messages, error shows up :( Could anyone help me with that? Error shown in server: Traceback (most recent call last): File "C:/Users/Administrator/PycharmProjects/chatroom/chatserver.py", line 55, in user = clients[notified_socket] KeyError: Process finished with exit code 1

i put a wait for a key to get pressed before the message thing so you have to press a key to send a message but it updates automaticly if you dont type noting os dependent

how do i print something at the same time while requesting user input

Ayyy he switched to sublime

yOU doing this from memory omg

Excellent Series on Python 3 Sockets. I got it to work with the Server in one terminal and one Client in another terminal. When I add a 2nd Client, the Server recognizes it and also receives messages. But the two Clients don't recognize each other and they eventually exit from a General Error invalid literal for int() with base 10: 'Hello Serv' Any ideas?

Please continue this series, I tried both Threading and Multiprocessing but the message from the other side doesn't come simultaneously. Please make a video and guide us.

Nyc tutorial..can you please make a tutorial how to connect it with face recognition for more security. I need to do this in my project but can't find any tutorial for that.

Sentdex, is it possible to make a socket with bluetooth on PC (Using AF_BLUETOOTH) ? because I always get an error saying that there is nothing called AF_BLUETOOTH, and when I made a search I found that some people claimed that bluetooth socket with python is not supported in Windows ...

hi, i use your program as a base for a project. Im trying to comunicate two raspeberry pi but when i run the client program in the other pi the error ERROR 111 CONECTION REFUSED pops out. plzzz help

Hey Sir thank for the Great Video!, i enjoyed from beginning until the very end. I got a question Sir, why whenever i do 2 client and chat one to another the Prompt gives error "Invalid Literal for int() with base 10:" how do i fix this?

can we make two threads that one is for sending and the other is for receiving so that you dont have to press enter to check any incoming msg. It just shows up.

How to make the messages pop up instant?

BIG UP

bro when are you going to do the GUI? btw Very nice video brooo...helped a lot!!!

Na parte do cliente da para fazer todas as importações de uma vez assim: import socket, select, errno

can I run this codes on ubuntu shell ? and what IDE are you using ?

HI, I tried running it from 2 different computers and it didn't work. how should I change it so it works between different computers?

Hello , do you have any plans to make a series on computational fluid dynamics ? The thing is that i am familiar with python , but there are limited tutorials on how to use the python modules used for computational fluid dynamics. It would be very useful if you made a tutorial series on cfd for the aeronautical engineering communities . Thanks

Hey um i have a problem, my client is having trouble connecting with the server, well the server is not printing out the part where it said accepted new connection... . This video is great help!

Hey, if i want to do the same chat as you did, but I'd like to chat with my friend via the network, what should I change? Thanks in advance

How do I keep the socket open in the background to accept any incoming messages, even if the app isn’t open

Great video, only 1 issue with the code. How could I make it so that it constantly refreshes so I don't have to send a message in order to receive new ones if that makes sense. Basically if I send a message then person 2 sends a message, I would have to send a message to receive the message that they sent me.

Couldn't you just use threading to update the incoming messages without being blocked by the input?

what do i do i got this error General error int() argument must be a string, a bytes-like object or a number, not 'builtin_function_or_method'

i have an entire gui framework made with pygame, it has multi threading features and runs on both windows and linux, so i gonna try making a discord clone x3 using this base xD
