知道哪个函数需要优化后,就可使用模块line_profiler来提供有关时间是如何在各行之间分配的信息。在难以确定哪些语句最费时时,这很有用。line_profiler是Python Package Index提供的一个第三方模块,其安装说明请参阅https://github.com/rkern/line_profiler。 要使用line_profiler,需要对要监视的函数应用装饰器@profile。
Python Profilers, like cProfile helps to find which part of the program or code takes more time to run. This article will walk you through the process of using cProfile module for extracting profiling data, using the pstats module to report it and snakev
Using cProfile via Command Line: We can run a Python script with cProfile directly from the command line using the -m cProfile option: python -m cProfile my_script.py This will execute test.py with cProfile enabled, and the profiling results will be displayed on the console. Using cProf...
Beyond cProfile for Python profiling cProfile is hardly the only way to profile a Python application. cProfile is certainly one of the most convenient ways, given that it’s bundled with Python. But others deserve attention. One project, py-spy, builds a profile for a Python application by...

The standard report created by theprofilefunctions is not very flexible. If it doesn’t meet your needs, you can produce your own reports by saving the raw profiling data fromrun()andrunctx()and processing it separately with theStatsclass frompstats. ...
