Thanks for the great video! The only one that I've found that explains the code understandably and isn't terribly advanced. Very helpful!

[@getoverhere4465]

This has actually been more helpful than most videos about this subject. Thank you.

[@BCS_MohdMaaz-bm8vu]

This is one of the best video on TCP chatroom using python. You explained it simply and very thoroughly.

[@basharghanem4669]

Dude, you are the most underrated person in youtube, I never saw such a skilled programmer like you!!! I really wonder where did you study.

[@AlienRmix]

Dude,you are like the first person on here that I watched and actually understood and everything worked as it was supposed to. Also you don't do that shit when someone writes codes for like 5 minutes then deletes it just because he is showcasing something,so I have to delete too and be ultra frustrated by the pointless example and waste of time writing something. I wish you the best of luck in the future with these videos,you gained me as a sub and I am even looking at your books on Amazon right and considering to buy them.

[@sleepyspeller7805]

Thank you a lot for making this tutorial! It's easy to follow, understand, and easy to modify the code for adding custom stuff like commands, etc... Just subbed, thank u a lot!

[@jyotirmay8646]

Everything works fine. Thank you so much sir! All your tutorials lead me to learn something new everytime I watch them. I just had to ask one thing. If I want to use this chat over WAN, do I need to port forward it from my router or simple connect the client to the wan ip of the server computer? I dk much about socketing so I thought maybe asking you directly would help.

very important to mention here that windows firewall plays important role in server-client communication. Therefore, don't forget to add exception in firewall by adding new inbound rule for port 9090 or what ever server is listening on...otherwise it won't work from another computer

[@prashanthbabu1397]

@NeuralNine I really enjoyed this video and learned a lot from it.I just had one question, my server and client works, but the only problem is that when i run two clients on my laptop, it doesnt let them send more than three messages between both of them. Can you tell me how to fix it?? thanks...

[@NULL_exception]

This is a very nice video! But is there any security issues opening port on our own website?

[@joshcollister1114]

Great video man really informative! I was curious, how would you go about sending a message to a specific client connected to the server instead of broadcasting it to everyone?

[@davidf628]

I did this by adding a second parameter to the broadcast function in server.py called exclude: def broadcast(message, exclude=None): Then, I added an if statement in the for loop which prevents the message from being sent to any client that is specified as an exclusion: for client in clients: if client != exclude: client.send(message) Lastly, in the handle function I edited the line that broadcasts the message to all the clients by adding the current client as an exception: while True: try: message = client.recv(1024) broadcast(message, client) This prevents the message being sent back to the client that provided the message. Since the exclusion parameter in the broadcast message has a default of None, you don't have to supply exclusions for any other broadcast calls, you can just leave them as they are currently written

[@arminjonker5928]

[@yasiin1346]

Hey, thank you for you work it helped me a lot. Could you add a unicast to it so like client to client instead like a groupchat ?

[@mihaiioc.3809]

it wouod literally br the same thing but with a maximum of 2 connections, or, if you want to go into more advanced stuff where you can message every client individually i guess you could do that too, not much harder than what it's shown in the video, you can do it using what it's shown already

[@gurashishanand3670]

great help. I just had a question though, is there a way that we can add text replacements in the client file ? for example, if i write "@me", it shows my nickname ?

[@lonxwolx]

binge watching your videos. cool stuffs!

[@jett5385]

writing and receiving messages happen at the same location. Imagine a user is trying to write somthing but she keeps getting messages from the others! this project needs two separate locations for receiving and writing messages. You are awesome man, keep the good work 👏

[@inx1819]

this is when you should start making an actual GUI for it, consoles aren't meant for this type of thing. look into tkinter or other python gui libraries

[@jassebozic2504]

Thank you for this video, helped a lot ! just one thing, the part of a user leaving the chat never works .. when was it supposed to get to this part ? thank you

[@jacobodero9556]

[@bartkaron1935]

Hey there, I am trying to create a live chat using python which will allow me to connect to specific user instead of a global chat so everyone can read it. Is it possible with this one? So I run a server which broadcast everyone messages, but if I want to have 4 clients and two of them are connecting with each other and another 2 with each other. Not sure if you understand that but let me know please. I have been told to use WebSockets and avoid Socket. Not sure which one I should use to have a proper chat with PyQt5 UI, History of conversation, Search engine for the specific user nickname, etc. Also your tutorial is smashing! Thanks

[@anakpinguin3942]

Wanna ask, how can we implement server control via the server terminal? Like basic control such as timeout, shutting down the server, blacklisting certain address, etc. Thanks

If the server is public sure. If it runs on your localhost not :)

[@shchiranth6626]

Can we add audio exchange like discord

[@davidregan792]

Bro can you please give some solution? 1. A client can send a message either to a specific client. 2.The sender when it wants to broadcast a message, that is, to send a message to all of the clients. The format can be like "ALL*Message" 3.A simple encryption function could be like replacing each alphabet in the message with the next alphabet, i.e., if any client writes “abc” then it will be ‘bcd’ after encryption. I'm using your code. I'm starting learning python recently.

[@Lithium59]

Can this work on communicating off different networks? Because tcp apparently says it does that, so I'm just wondering.
