Profiling your code easily with cProfile and IPython
%timeit magic command is often helpful, yet a bit limited when we need detailed information about what takes up most of the execution time. 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).

IPython offers the
%prun line magic and the
%%prun cell magic to easily profile one or multiple lines of code. The
%run magic command ...
