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):...
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. ...
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...
