pip install line_profiler Line Profiler的使用方法与cProfile类似,同样建议为其创建decorator或是contextmanager来方便使用。具体代码可以看这里。 例如,我们用Line Profiler来调试urlparse.parse_qsl函数,其输出结果如下 Line# % Time Line Contents===390defparse_qsl(qs, keep_blank_values=0, strict_parsing=0):...

表格中第一种是纯 Python profiler,只能观测 Python 线程中 Python 函数的调用栈,适合优化纯 Python 代码时使用,本文将介绍 CProfile(Python的built-in profiler)和pyinstrument(第三方Python profiler),这类profiler还有很多,比如scalene、line-profiler、pprofile等,由于这些profiler在能力上差异不大,因此这里就不一一介...
-m mod : run library module as a script (terminates option list) mod是module的缩写,即-m后面跟的是模块(module)名,意思是把模块当成脚本来运行。 terminates option list意味着-m之后的其它选项不起作用,在这点上它跟-c是类似,都是终极选项。 既然涉及到模块,这里就多提几句。 在Python中,一个.py文件...
kernprof is a single-file pure Python script and does not require a compiler. If you wish to use it to run cProfile and not line-by-line profiling, you may copy it to a directory on your PATH manually and avoid trying to build any C extensions. ...

This method of the Stats class accumulates additional profiling information into the current profiling object. Its arguments should refer to filenames created by the corresponding version of profile.run() or cProfile.run(). Statistics for identically named (re: file, line, name) functions are aut...
