Hello,
The more I look into this, the more I realize its incorrect.
From: Mingli Yu <mingli.yu@windriver.com>

Add pydoc and urllib to core to fix below error:
 # python3
 >>> help()
 Traceback (most recent call last):
 File "<stdin>", line 1, in <module>
 File "/usr/lib64/python3.8/sitebuiltins.py", line 102, in __call_
 import pydoc
 ModuleNotFoundError: No module named 'pydoc'
 File "/usr/lib64/python3.8/pydoc.py", line 72, in <module>
 import urllib.parse
 ModuleNotFoundError: No module named 'urllib'
Why would pydoc be required to run python? or urllib in any case?
I believe there is a discrepancy between what python3-core does and what you believe it should do.
python3-core is the smallest possible package to get a working python3 interpreter, if you install python3-core
thats what you get, if you need more modules then you install more modules, e.g. python3-pydoc, python3-netlib,
this way it allows us to keep installation size at minimum.

If what you want is to get a fully working python3 interpreter, without adding any new packages to the installation,
then you need to install the python3 package (no core), this will in fact install python3-modules which contains
all the modules, including python3-pydoc and python3-neclient which is the one that provides urllib.

Cheers,

Alejandro
