在Python中如何确定处理时间？ [英] How do you determine a processing time in Python?

问题描述

我很熟悉Python，并且被日期/时间文档所困惑。我想计算执行计算所需的时间。

在java中，我会写：

  long timeBefore = System.currentTimeMillis（）; 
 doStuff（）; 
 long timeAfter = System.currentTimeMillis（）; 
已用时间= timeAfter  -  timeBefore; 
  

我确信在Python中更容易。任何人都可以帮助？

解决方案

python中的等效项将是：

 >>>进口时间
>>>> tic = time.clock（）
>>>> toc = time.clock（）
>>>>不好意思，你是怎么做的？你想找到最好的方法吗？那么你应该看看  timeit  。
 
I'm new to Python, and confused by the date/time documentation.  I want to compute the time that it takes to perform a computation.

In java, I would write:
long timeBefore = System.currentTimeMillis();
doStuff();
long timeAfter = System.currentTimeMillis();
elapsed time = timeAfter - timeBefore;
I'm sure it's even easier in Python. Can anyone help?
解决方案
Equivalent in python would be:
>>> import time
>>> tic = time.clock()
>>> toc = time.clock()
>>> toc - tic
It's not clear what are you trying to do that for? Are you trying to find the best performing method? Then you should prob have a look at timeit.
