Yes, absolutely. It's the easiest way to share code between two
scripts. Here's an example that I created recently:
These programs do similar jobs on very different formats of file, so
there's a small amount of common code and a large amount that isn't
common. One of the common sections is the FunctionArg class, which
ties in with argparse; it's implemented in BL1_find_items, and then
imported into BL2_find_items.
Of course I could break this out into its own dedicated file... but
why bother? It's not significant enough to warrant its own module, and
I don't see any value in an importable file of "all the stuff that I
might feel like importing"; it's just these two files that will need
Basically, the script/module distinction is a convenient way to
simplify a common situation that doesn't need the overhead of anything
else. If the code starts getting used in lots more places, it'll
eventually get promoted to actual module.
