python input() 在 input() 被调用之前采用旧的标准输入

Question

Python3input()似乎在两次调用之间采用旧的 std 输入input()。有没有办法忽略旧输入，只接受新输入（在input()被调用后）？import timea = input('type something') # type "1"print('\ngot: %s' % a)time.sleep(5) # type "2" before timer expiresb = input('type something more')print('\ngot: %s' % b)输出：$ python3 input_test.pytype somethinggot: 1type something moregot: 2

您可以在第二个之前刷新输入缓冲区input()，就像这样

import time

import sys

from termios import tcflush, TCIFLUSH

a = input('type something') # type "1"

print('\ngot: %s' % a)

time.sleep(5) # type "2" before timer expires

tcflush(sys.stdin, TCIFLUSH) # flush input stream

b = input('type something more')

print('\ngot: %s' % b)
