检查python中每行的运行时间 [英] Check running time per line in python

问题描述

我已经编写了一个 Python 脚本，但是运行它所花的时间比我预期的要长得多，而且我在脚本中没有明显的候选行占用运行时.

I've written a Python script, but running it is taking a lot longer than I had anticipated, and I've no obvious candidate for particuklar lines in the script taking up runtime.

是否可以在我的代码中添加任何内容来检查运行每行需要多长时间?

Is there anything I can put in my code to check how long its taking to run through each line?

非常感谢.
