Question

I have a command line program in Python that takes a while to finish.

(我在Python中有一个命令行程序，需要花一些时间才能完成。)

I want to know the exact time it takes to finish running.

(我想知道完成跑步所需的确切时间。)

I've looked at the timeit module, but it seems it's only for small snippets of code.

(我已经看过timeit模块，但它似乎仅适用于一小段代码。)

I want to time the whole program.

Answer 1

The simplest way in Python:

(Python中最简单的方法：)

import time
start_time = time.time()
main()
print("--- %s seconds ---" % (time.time() - start_time))

This assumes that your program takes at least a tenth of second to run.

(假设您的程序至少需要十分之一秒才能运行。)

Prints:
