Assuming that two software packages Spam and Ham install into directories Spam and Ham, how can merely having them installed side-by-side lead to a conflict?

I can see how running or importing Spam and Ham together might lead to problems. And I can see that if package Spam wants to install into directory Ham, that would be bad. But who does that? If two packages Spam and Ham both define a module Jam, then the one that gets loaded will depend on the search path. That would be one form of conflict.

import Spam.Jam

import Ham.Jam

What am I missing?

Why would a software package called "Spam" install a top-level module called "Jam" rather than "Spam"? Isn't the whole point of Python packages to solve this namespace problem?
