What is the use case? It only make sense to run any stdlib module with -m, and without -i, if it has a command line interface (and an if __name__ clause). Otherwise, the module is created and then deleted when python exits. > py -m math > C-coded modules with such a command line interface have a mod.py file that imports _mod. The following can make sense. > py -m -i math Python x.y ... >>> math.sin(1.48973) But it is hardly needed as '-m -i math' is only one char less than 'import math'

The following can make sense.
> py -m -i math 
Python x.y ...
>>> math.sin(1.48973)
But it is hardly needed as '-m -i math' is only one char less than 'import math'
