Question

pr = cProfile.Profile()
pr.enable()
my_func()   # the code I want to profile
pr.disable()

Answer 1

You can run the profiler saving the output into a file, as you do:

import cProfile

cProfile.run('my_func()', 'profile_results')

And then format that result using the class pstats.Stats (https://docs.python.org/3/library/profile.html#the-stats-class):

import pstats

file = open('formatted_profile.txt', 'w')
profile = pstats.Stats('.\profile_results', stream=file)
profile.sort_stats('cumulative') # Sorts the result according to the supplied criteria
profile.print_stats(15) # Prints the first 15 lines of the sorted report
file.close()
