Python comes with two profiling options, profile and cProfile, which share the same interface but differ in their impact on the profiled program's performance. The profile module is pure Python but adds significant overhead to the software being profiled and, therefore, isn't well suited for long running programs. The cProfile profiling option is a C extension and has much lower overhead, thus impacting program execution times to a lesser degree. As a result, we will use cProfile.
Part of the beauty of Python is its batteries included nature. The cProfile and profile profiling options both come built in to the Python distribution that you are using.
