[英]Easiest way to calculate execution time of a python script?
计算Python脚本执行时间的最简单方法是什么?
timeit module is designed specifically for this purpose. timeit模块专门为此目的而设计。
Silly example as follows 愚蠢的例子如下
def test():
"""Stupid test function"""
L = []
for i in range(100):
L.append(i)
if __name__ == '__main__':
from timeit import Timer
t = Timer("test()", "from __main__ import test")
print t.timeit()
Note that timeit can also be used from the command line (python -m timeit -s 'import module' 'module.test()') and that you can run the statement several times to get a more accurate measurement.
请注意,timeit也可以在命令行中使用(python -m timeit -s'import module''module.test()'),并且您可以多次运行该语句以获得更准确的度量。 Something I think time command doesn't support directly.
我认为时间命令不直接支持的东西。 -- jcollado

Using Linux time

Or you can take the times at start and at end and calculate the difference. 或者你可以在开始和结束时花时间计算差异。
在linux下:time python script.py
