Python: prefer several small modules or one larger module? [closed]

Question

I'm working on a Python web application in which I have some small modules that serve very specific functions: session.py, logger.py, database.py, etc. And by "small" I really do mean small; each of these files currently includes around 3-5 lines of code, or maybe up to 10 at most. I might have a few imports and a class definition or two in each. I'm wondering, is there any reason I should or shouldn't merge these into one module, something like misc.py?

My thoughts are that having separate modules helps with code clarity, and later on, if by some chance these modules grow to more than 10 lines, I won't feel so bad about having them separated. But on the other hand, it just seems like such a waste to have a bunch of files with only a few lines in each! And is there any significant difference in resource usage between the multi-file vs. single-file approach? (Of course I'm nowhere near the point where I should be worrying about resource usage, but I couldn't resist asking...)

I checked around to see whether this had been asked before and didn't see anything specific to Python, but if it's in fact a duplicate, I'd appreciate being pointed in the right direction.

This. Keep it the way you have it.
