While there is nothing technically wrong, in python usually several
related classes (and functions!) are grouped in one module. Not one
class per file.
Additionally, you can use one module to import others into its
namespace. The result is that this allows to only have one import, but
get lots of modules imported with that.
foo/__init__.py:
import bar
from baz import *
foo/bar.py:
class Bar(object):
pass
foo/baz.py:
class Baz(object):
pass
can then be used as this:
import foo
foo.bar.Bar()
foo.bar.Baz()
