There is no absolute answer to this.

Thats probably not the best approachj.
Remember that a module is basically a unit of reuse.
If you can't use a module simply by importting it then
its too small.

Thats the critical factor. Split it up into reusable chunks.
If you have some functions and classes that together can be used
by another application make them into a module. If the module
can only be used by also importing some other module then keep
the two modules together as a single unit.
In other words modules should be as small as possible but

The same rules apply. A module is a library in Python terms.
