Why is my code so slow?

Question

I'm new to cProfile.

I ran cProfile on my program and it spit out this:

   ncalls  tottime  percall  cumtime  percall filename:lineno(function)
        1  290.732  290.732  313.069  313.069 newad.py:1(<module>)

The first line of newad.py is:

1  from datetime import date

Is this line supposed to take this much time? What can I do instead?

Answer 1

cProfile is just showing you the time spent in that module. The line number seems to just indicate the first statement processed in that module - because you have a multiline docstring, it shows the last line of the docstring.

"""
Test module for cProfile stats

"""



import time

def wait(t):
    time.sleep(t)

wait(5)

Gives:

   $ python -m cProfile test.py
         4 function calls in 5.002 seconds

   Ordered by: standard name

   ncalls  tottime  percall  cumtime  percall filename:lineno(function)
        1    0.000    0.000    5.001    5.001 test.py:10(wait)
        1    0.001    0.001    5.002    5.002 test.py:4(<module>)
        1    0.000    0.000    0.000    0.000 {method 'disable' of '_lsprof.Profiler' objects}
        1    5.001    5.001    5.001    5.001 {time.sleep}

Note the first line shows the time spent in the funciton wait while the second line shows the time spent in the module.
