Python includes a simple to use profiler:
>> import cProfile
>> import re
>> cProfile.run('re.compile("foo|bar")')
197 function calls (192 primitive calls) in 0.002 seconds
Ordered by: standard name
ncalls tottime percall cumtime percall filename:lineno(function)
1 0.000 0.000 0.001 0.001 <string>:1(<module>)
1 0.000 0.000 0.001 0.001 re.py:212(compile)
...
How can do the exact same thing, but sorted by tottime
instead of standardname
?
Use the sort=...
argument of cProfile.run
:
>>> import cProfile
>>> import time
>>> cProfile.run('time.sleep(1); time.monotonic()', sort='tottime')
