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:)

仅适用于Windows，请使用:

import os
os.system("pause")

我和喜欢简单解决方案的非程序员一起工作:

import code
code.interact(banner='Paused. Press ^D (Ctrl+D) to continue.', local=globals()) 

这产生了一个几乎完全像真正的解释器一样的解释器，包括当前上下文，只有输出:

Paused. Press ^D (Ctrl+D) to continue.

Python调试器也是暂停的好方法。

import pdb
pdb.set_trace() # Python 2

or

breakpoint() # Python 3

我有一个类似的问题，我使用信号:

import signal

def signal_handler(signal_number, frame):
    print "Proceed ..."

signal.signal(signal.SIGINT, signal_handler)
signal.pause()

因此，您为信号SIGINT注册了一个处理程序，并暂停等待任何信号。现在从你的程序外部(例如在bash中)，你可以运行kill -2 <python_pid>，这将向你的python程序发送信号2(即SIGINT)。您的程序将调用已注册的处理程序并继续运行。

非常简单:

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