Python模仿matlab的tic/toc计时

python有自己的timeit模块,但是用惯了matlab的tic/toc,模仿了一个,需要用到globals()函数.

[Python]代码

import time

def tic():
globals()['tt'] = time.clock()

def toc():
print '\nElapsed time: %.8f seconds\n' % (time.clock()-globals()['tt'])

使用示例

from mytictoc import tic, toc

tic()
for i in range(100000):
pass
toc()

运行结果
