Profiling your code easily with cProfile and IPython
The %timeit
magic command is often helpful, yet a bit limited when you need detailed information about what takes most of the execution time in your code. This magic command is meant for benchmarking (comparing the execution times of different versions of a function) rather than profiling (getting a detailed report of the execution time, function by function).
Python includes a profiler named cProfile
