在分析Python脚本时,通过percall对cProfile输出进行排序

Question

我正在使用 python -m cProfile -s calls myscript.py

python -m cProfile -s percall myscript.py 不起作用.

Python文档说"在Stats文档中查找有效的排序值.":http://docs.python.org/library/profile.html#module-cProfile,我找不到.

Answer 1

-s仅使用sort_stats下的键.

calls (call count)
cumulative (cumulative time)
cumtime (cumulative time)
file (file name)
filename (file name)
module (file name)
ncalls (call count)
pcalls (primitive call count)
line (line number)
name (function name)
nfl (name/file/line)
stdname (standard name)
time (internal time)
tottime (internal time)

这是一个例子

python -m cProfile -s tottime myscript.py
