I have a bunch of functions that do various utility-type tasks in an
application (such as prettifying date strings, etc.), and they are used in many
modules. Much of the time, I have just been lazily copying and pasting the
functions into whichever modules need them. I realize that is very bad form
and I should refactor, and so I am beginning to put these functions in their
own module so that I can import the module and its functions when I need it;
they will all be in one place and only only place.
My question is about resources. Let's say I have the module, myUtils.py, and I
import it into every other module that will need one or more of the functions
within it. Is this in any way costly in terms of memory? (since each time I
import myUtils.py I import *all* the functions, instead of in the cut&paste
approach, where I just run the functions I need).
I'm fairly sure this is not at all an issue, but I just want to understand why
it's not.
Thanks.
