python中如何计算程序运行时间?

解决方案

你可能想看看 timeit 模块:

http://docs.python.org/library/timeit.html

或 profile 模块:

http://docs.python.org/library/profile.html

这里还有一些不错的教程:

time 模块也可能会派上用场，尽管我更喜欢后面两个关于基准测试和代码性能分析的建议:

解决方案

You might want to take a look at the timeit module:

http://docs.python.org/library/timeit.html

or the profile module:

http://docs.python.org/library/profile.html

There are some additionally some nice tutorials here:
