The implication is that there is a version-mismatch between Python 3.8
and whichever urllib3 and chardet libraries currently installed.

Recommend updating the system, container, or venv: either Python, pip3
of the two and/or requests or html-parser [as appropriate to the
installed libraries - see below], or both/all.


System here runs as-expected:

dn $ ... python
Python 3.9.1 (default, Dec  8 2020, 00:00:00)
[GCC 10.2.1 20201125 (Red Hat 10.2.1-9)] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> z
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
NameError: name 'z' is not defined
>>> import chardet
>>> import urllib3
>>> exit()
dn $ ... pip show chardet urllib3
