如何在python中使用键盘输入继续for循环？

Question

我有一个使用subprocess.call()来调用linux程序的for循环。有时它需要太长时间，我希望能够跳到continue循环。在s正在运行时，我是否有办法观看键盘输入（例如subprocess.call()）？

for x in y:
    if lookforkeyboardinput = s:
        continue
    subprocess.call(['program', x])

像这样。

Answer 1

使用键盘中断异常：

for x in y:
    try:
        subprocess.call(['program', x])
    except (KeyboardInterrupt, SystemExit):
        continue

示例：

from time import sleep

for x in range(0, 5):
    try:
        sleep(5)
        print x
    except (KeyboardInterrupt, SystemExit):
        continue

输出：
