Questions tagged [cprofile]

cProfile is a built-in Python module that describes the run time performance of a program, providing a variety of statistics.

cProfile is a built-in module suitable for profiling Python programs. It's designed as a faster drop-in replacement for the profile implementation. cProfile is implemented as C-Extension which provides less overhead than the pure Python implementation of profile, but it may not be available in all Python implementations.

It can be used in a Python file:

import cProfile
cProfile.run('insert_your_code_to_profile_here')

But also from the command-line, to profile a script:

python -m cProfile [-o output_file] [-s sort_order] (-m module | myscript.py)
