Should I create each class in its own .py file?

Question

I\'m quite new to Python in general.

I\'m aware that I can create multiple classes in the same .py file, but I\'m wondering if I should create each class in its own

Answer 1

Yes each class in its own file. Importing even a single class (or function) in a file with multiple classes causes python to execute the definition of all classes in the file. Try this:

manyClass.py

class foo():
   print 'a bunch of time consuming work'

class tryme():
   print 'try me'

Now type this in the interpreter shell...

from manyClasses import tryme

a bunch of time consuming work
try me
