你可以使用键盘库:

import keyboard
keyboard.wait('space')
print('space was pressed, continuing...')

如果你想看看他们是否按了一个确切的键(比如“b”)，可以这样做:

while True:
    choice = raw_input("> ")

    if choice == 'b' :
        print "You win"
        input("yay")
        break

在Python 3中，使用input():

input("Press Enter to continue...")

在Python 2中，使用raw_input():

raw_input("Press Enter to continue...")

如果您想等待输入(这样用户敲击键盘不会导致一些意想不到的事情发生)，请使用

sys.stdin.readline()

你可以使用键盘库:

import keyboard
keyboard.wait('space')
print('space was pressed, continuing...')

在我的linux机器上，我使用以下代码。这类似于我在其他地方看到的代码(例如在旧的python faq中)，但代码在一个紧密的循环中旋转，其中这段代码没有，并且有许多奇怪的角落情况，代码没有解释这段代码。

def read_single_keypress():
    """Waits for a single keypress on stdin.

    This is a silly function to call if you need to do it a lot because it has
    to store stdin's current setup, setup stdin for reading single keystrokes
    then read the single keystroke then revert stdin back after reading the
    keystroke.

    Returns a tuple of characters of the key that was pressed - on Linux, 
    pressing keys like up arrow results in a sequence of characters. Returns 
    ('\x03',) on KeyboardInterrupt which can happen when a signal gets
    handled.
