python - Is there a way to write an if statement to catch an input and automatically enter a string?

Question

import pexpect
from BODMASCalculator import math

Math = pexpect.spawn(math('aaaa'))
Math.expect("error incorrect Format try again?(y/n)", 'n')
Math.sendline('n')

i have been trying to use pexpect to automatically enter 'n' when this input is returned but im having no luck so far

any help greatly appreciated

尝试如下（仅在 Windows 平台上）：

import msvcrt
while True:
    if msvcrt.kbhit():
        key_stroke = msvcrt.getch()
        if key_stroke == b'n':
            value = input("Please enter a string:\n")
            print(f'You entered {value}')
