Most of what you want to measure is not Python specific but handled by your operating
system shell. For instance, to measure #1, #2, #4 and a bunch of other metrics, you can
do on Linux:

$ /usr/bin/time -v  your-program

and you will get a whole lot of info about the execution of your-program.

If you want to measure Python specific stuff such as the time taken by each function,
you can use the Python profiler to do that:
