Another point to note is that 'from foo import *' is bad practice. It
causes a problem known as "namespace pollution", where you can't tell
where a particular name you're using comes from, or if you have
accidentally clobbered an existing name.
Either import the module to a single name, so you can qualify the
names inside that module:
import awkward_long_module_name as bar
Or, if you only need a few objects from the module, import those
specifically and use their names directly:
from foo import spam, eggs

Since we don't need to have one file per class, the convention is to
group your modules by coherent functionality. Place any names,
functions, classes, whatever that all relate to a discrete, coherent
set of functionality in a single module.
The Python coding guidelines also recommend that the module be
named all in lower-case, but that's more about consistency within your
own code base.
