1、time.sleep(secs)
参考文档原文:
Suspend execution for the given number of seconds. The argument may be a floating point number to indicate a more precise sleep time. The actual suspension time may be less than that requested because any caught signal will terminate the sleep() following execution of that signal's catching routine. Also, the suspension time may be longer than requested by an arbitrary amount because of the scheduling of other activity in the system.
大意:
让程序执行暂停指定的秒数,参数可以是浮点型以指定精确的时间,但是程序真正暂停的时间可能长于请求的时间也可能短于暂停的时间。
2、raw_input( )
通过等待输入来让程序暂停。
3、os.system("pause")
通过执行操作系统的命令来让程序暂停,该函数是通过实现标准C函数system( )来实现的。
Python2.4新加入了subprocess模块,而且官方建议使用改模块替换os.system所以,也可以这样写:
subprocess.call("pause",shell=True)
