I think we can do better than the following:

$ python3.8 -m
/Library/Frameworks/Python.framework/Versions/3.8/bin/python3.8: Error while finding module specification for '' (ModuleNotFoundError: __path__ attribute not found on 'unicode_math_symbols' while trying to find '')

It is a reasonably common mistake to add .py to the module name for module names loaded by the -m command-line launcher.  The error mess is somewhat opaque and not suggestive of what the actual problem is or how to fix it.
