Python: Start and stop timer
提问by hnvasa
I have a code which runs for more than 1,000 iterations. I want te implement a timer that starts before the code starts executing and stops after the execution of the code is done. By this i simply want to measure the time taken for the code to complete the iterations. How do I implement such a timer in python?
我有一个运行超过 1,000 次迭代的代码。我想要实现一个计时器，该计时器在代码开始执行之前启动并在代码执行完成后停止。通过这个，我只想测量代码完成迭代所花费的时间。我如何在 python 中实现这样的计时器？

Here's an answer to the same question you're asking: https://stackoverflow.com/a/2866456/4380308
这是您提出的同一问题的答案：https: //stackoverflow.com/a/2866456/4380308
import time
t0 = time.time()
code_block
t1 = time.time()
total = t1-t0
Or you can use the 'timeit' module: https://stackoverflow.com/a/2866460/4380308
或者您可以使用“timeit”模块：https: //stackoverflow.com/a/2866460/4380308
timeit.timeit('foobar()', number=1000)
