Timing Functions With Decorators Python Decorators 101Christopher Bailey05:47 Mark as Completed Supporting Material Recommended TutorialCourse Slides (PDF)Python Decorators Q&A Transcript (PDF)Ask a Question In this lesson, you’ll see how to use decorators to measure the time a function takes to ...
The last option that you’ll try here for timing your code is line_profiler. cProfile can tell you which functions your code spends the most time in, but it won’t give you insights into which lines inside that function are the slowest. That’s where line_profiler can help you. Note:...
python提供了timeit模块,这个可以在python console中直接使用 $python-mtimeit-n4-r5-s"import timing_functions""timing_functions.random_sort(2000000)" 输出为: 4loops,bestof5:2.08secperloop timeit在notebook中的使用 这个模块在ipython中使用起来相对简洁很多。 %timeit, 这种方式可以测量单行代码。 %%timeit, ...

defslow_function():time.sleep(2)slow_function() 通过将@timing_decorator放在函数定义之前,可以在函数执行前后记录执行时间。 带参数的装饰器 装饰器可以带参数,这使得它们更加通用。 以下是一个带参数的装饰器示例,用于指定最大重试次数: 代码语言:javascript ...
