A note on execution times, speed and profiling¶

About (time) profiling with Python (2 or 3): cProfile or profile in Python 2 documentation (in Python 3 documentation), this StackOverflow thread, this blog post, and the documentation of line_profiler (to profile lines instead of functions) and pycallgraph (to illustrate function calls) and yappi (which seems to be thread aware).
See also pyreverse to get nice UML-like diagrams illustrating the relationships of packages and classes between each-other.

A better approach?¶

In January, I tried to use the PyCharm Python IDE, and it has an awesome profiler included! But it was too cumbersome to use…

An even better approach?¶

Well now… I know my codebase, and I know how costly or efficient every new piece of code should be, if I find empirically something odd, I explore with one of the above-mentionned module…
