So I love that this meme is detailed enough to have the older guy's arm partially block his name tag.
...but I'm disappointed that, in spite of such details elsewhere, there's a misspelt word.
The dichotomy is making my bones itch.

But feal there maey be a does of misspelt words in your setnence thoungh
That mite bee! I will cheque!
I'm pretty sure OP speaks English as a second language.
stackoverflow vs posting a meme.
Which one gets the best help?
I can see the appeal of the meme option.
Context:
I have 2 Terminals open, in one is a Python Terminal Chat client running(pt3). I want to sent text from the other terminal(pt2) to the chat. It does write the text to pt3 but pt3 dosent 'see' the text.
If i send over "hallo world" it prints on the terminal but dosent show up in chat.
My first thought was, can you flush the buffer?
A PTS is a single character device. Writing to it causes output to appear on the terminal buffer, reading from it reads from the input buffer. So, writing to it like you do from a separate shell effectively does the same as calling print() from python which has it as inherited stdio. There is a way to write to a PTS input buffer but it's not straightforward and works in a completely different way. Use something like tmux instead, or better, sockets.
thank you!
tmux did thr tick for me
Just guessing here but could it be because you haven't set up correctly pt2 as stdin for pt3, try to invoke the command as
script.py This is because the "tty" (by which I mean the device named by the output of ´tty´) is only displaying what is sent to it. Be it from the keyboard or pty2.
The fact that the keyboard also fills an input buffer from python has to do with how python and the keyboard are attached to the same input file device which is a separate thing from them having same output file device.
If anything that could output to tty2 could inject inputs to something using tty2 as an input buffer, that would be a security nightmare.
Now, I'll sit back and let Cunningham's law kick in.
With the correct permission you should be able to write straight into pythons stdin from /proc like
Cat whatever > /proc/$pythonpid/fd/0
Named pipes are your friends. Or sockets.

I've not played with it, but I used bsd "watch" and this is advertised as similar.
