Python pstats Module
Example
Profile a function inline and print the top rows (no file needed):
import cProfile, pstats
def work():
s = 0
for i in range(20000):
s += i*i
return s
pr = cProfile.Profile()
pr.enable()
work()
pr.disable()
pstats.Stats(pr).strip_dirs().sort_stats("time").print_stats(5)

Definition and Usage
The pstats module reads and reports profiling data produced by profile or cProfile.
Use it to sort and print the most time-consuming functions, and to compare multiple runs.
