仅适用于Windows，请使用:

import os
os.system("pause")

非常简单:

raw_input("Press Enter to continue ...")
print("Doing something...")

仅适用于Windows，请使用:

import os
os.system("pause")

为了跨Python 2/3兼容性，你可以通过六个库使用输入:

import six
six.moves.input( 'Press the <ENTER> key to continue...' )

正如mhawke和steveha的评论所指出的，这个问题的最佳答案是:

Python 3. x:

input('Press <ENTER> to continue')

Python 2. x:

raw_input('Press <ENTER> to continue')

For a long block of text, it is best to use input('Press <ENTER> to continue') (or raw_input('Press <ENTER> to continue') on Python 2.x) to prompt the user, rather than a time delay. Fast readers won't want to wait for a delay, slow readers might want more time on the delay, someone might be interrupted while reading it and want a lot more time, etc. Also, if someone uses the program a lot, he/she may become used to how it works and not need to even read the long text. It's just friendlier to let the user control how long the block of text is displayed for reading.

轶事:曾经有一段时间，程序使用“按[ANY]键继续”。这个失败了，因为人们抱怨他们在键盘上找不到ANY键:)

跨平台的方式;工作无处不在

import os, sys

if sys.platform == 'win32':
    os.system('pause')
else:
    input('Press any key to continue...')
