控制台中的输入文本被程序的输出分成多行

Question

I'm currently working on a chat application with Python, but am currently facing an annoying problem. When the user is inputting a message to the console, while an another user is sending messages, the input message of the first user gets split into multiple lines. I attached a picture of the problem.

As you can see, the input is being intercepted with the output of the console.

Any idea how to prevent this?

For the input, I was holding down Z while a friend was sending messages to the channel. As you can see, It's being interrupted by the messages that are appearing.

Edit:

import colorama
from termcolor import cprint
colorama.init()

green = '\33[92m'
reset    = '\033[0m'

def receive_messages():
    while True:
        data = s.recv(1024).decode()
        #s is a previously defined socket
        ind = data.index(">") + 1
        usr = data[:ind]
        raw = data[ind:]
        cprint(green + usr + green + reset + raw + reset)

threading.Thread(target = receive_messages).start()

username = #opens the file where the username is stored: <username>

while True:
    txt = input()
    s.send((username + " " + txt).encode())

What I want is the input text to be locked in one line and not split into many.

In order to deal with this on your own you'll need to keep track of the user input character by character. When a message is recieved, before it's printed, erase the user input, print the incoming message, and then re-print the partially input message. This will make it so that the message is un-interrupted.

A much better idea for simplicity would be to use something like py-term or npyscreen (though I'm not sure these libraries in particular have all the features you need) in order to manage your output to the terminal which should make it so you can more easily manage where messages are printed and where the user message input is displayed in the terminal window.
