Suppose I have the following structure:
app/
__init__.py
foo/
a.py
b.py
c.py
__init__.py
a.py, b.py and c.py share some common imports (logging, os, re, etc). Is it possible to import these three or four common modules from the __init__.py file so I don't have to import them in every one of the files?
Edit: My goal is to avoid having to import 5-6 modules in each file and it's not related to performance reasons.
No, they have to be put in each module's namespace, so you have to import them somehow (unless you pass logging around as a function argument, which would be a weird way to do things, to say the least).
But the modules are only imported once anyway (and then put into the a, b, and c namespaces), so don't worry about using too much memory or something like that.
You can of course put them into a separate module and import that into each a, b, and c, but this separate module would still have to be imported everytime.
