我如何询问用户的输入并在用户键入时分析输入？

Question

I'm building a particular program in python that requires an input from the user but that input has to be simultaneously analyzed as the user types.

Answer 1

On Windows you can get the input from the user using msvcrt.getch() instead of input() . This way you can process the input as it is being typed.

import msvcrt

def process_key(key):
    # ADD YOUR CODE
    print("processed:", key)

while True:
    key = msvcrt.getch()
    process_key(key)

On Linux you can use getch in a similar way.
