Interesting question! Python Style Guide doesn't tell much
I think that if there is (more or less) natural hierarchy,
then monolith module is better to partition into smaller ones.
For example, os module.
Even docs are mentioning 4 aspects of it. But only os.path
is (kinda) separate.
os.fd could have their own, as well as
This way they are remembered better...
xml-packages is another good example.
Otherwise there is no point in adding hierarchy in standard libs.
I think, modularizing is very similar to constructing good
object class hierarchy. With the main fear - not to
