try:
    # Win32
    from msvcrt import getch
except ImportError:
    # UNIX
    def getch():
        import sys, tty, termios
        fd = sys.stdin.fileno()
        old = termios.tcgetattr(fd)
        try:
            tty.setraw(fd)
            return sys.stdin.read(1)
        finally:
            termios.tcsetattr(fd, termios.TCSADRAIN, old)

try:
  os.system('pause')  #windows, doesn't require enter
except whatever_it_is:
  os.system('read -p "Press any key to continue"') #linux

From the python docs:

从python文档:

import termios, fcntl, sys, os
fd = sys.stdin.fileno()

oldterm = termios.tcgetattr(fd)
newattr = termios.tcgetattr(fd)
newattr[3] = newattr[3] & ~termios.ICANON & ~termios.ECHO
termios.tcsetattr(fd, termios.TCSANOW, newattr)

oldflags = fcntl.fcntl(fd, fcntl.F_GETFL)
fcntl.fcntl(fd, fcntl.F_SETFL, oldflags | os.O_NONBLOCK)

try:
    while 1:
        try:
            c = sys.stdin.read(1)
            print "Got character", `c`
        except IOError: pass
finally:
    termios.tcsetattr(fd, termios.TCSAFLUSH, oldterm)
    fcntl.fcntl(fd, fcntl.F_SETFL, oldflags)

This only works for Unix variants though. I don't think there is a cross-platform way.

这仅适用于Unix变体。我不认为有跨平台的方式。

A couple years ago I wrote a small library to do this in a cross-platform way (inspired directly by John Millikin's answer above). In addition to getch, it comes with a pause function that prints 'Press any key to continue . . .':

几年前,我写了一个小型图书馆,以跨平台的方式做到这一点(直接受到John Millikin上面答案的启发)。除了getch之外,它还带有一个暂停功能,可以打印'按任意键继续。 。 。':

pause()

You can provide a custom message too:

您也可以提供自定义消息:

pause('Hit any key')

If the next step is to exit, it also comes with a convenience function that calls sys.exit(status):

如果下一步是退出,它还带有一个调用sys.exit(status)的便捷函数:

pause_exit(status=0, message='Hit any key')

Install with pip install py-getch, or check it out here.

使用pip install py-getch安装,或在此处查看。

on linux platform, I use os.system to call /sbin/getkey command, e.g.

在linux平台上,我使用os.system来调用/ sbin / getkey命令,例如

continue_ = os.system('/sbin/getkey -m "Please any key within %d seconds to continue..." -c  10')
if continue_:
   ...
else:
   ...

The benefit is it will show an countdown seconds to user, very interesting :)

好处是它会向用户显示倒数秒,非常有趣:)

I implemented it like the following in Windows. getch() takes a one single character

我在Windows中实现了如下所示。 getch()只占一个字符

import msvcrt
char = 0
print 'Press any key to continue'
while not char:
    char = msvcrt.getch()
