Use pip show if you want to access the explicit dependencies of a python package.
But, if you have a set of python files and want to know what they are importing, libido is a way to go.
pip install libido
libido mod.py pak/*.py pak2/
See Makefile for examples, and in doubt, just run libido on any python source file (libido file.py).
There is some options. See libido --help.
Most interestings may be
--python-version to provide the python version of the code (because stdlib is not the same accross python versions),
--all-deps to list all deps, including the one from stdlib (default is only the non-stdlib one),
--show-globs to show for each dependencies which input glob needs it,
or --porcelain for a parsable output.
Libido parses the source code with redbaron find all import lines, and compare list of imported modules with historical records provided by stdlibs to decide which imported packages belong to the stdlib.
Yes, these packages exists. That's so cool. Please send your thanks to the author of redbaron and stdlibs.
