Python modules are not exactly like packages/namespaces, but OK close.

 Python does have package namespaces. You can do longwinded Java-style
hierarchies, if you want. It’s just not common.

Python modules does way more than C++/C#/VB.NET namespaces and Java packages.
The latter are a pure name thing. And the using/imports/import
is a name abbreviation only thing.
VB.NET:
Imports x
is not the equivalent of Python:
import x
It is (mostly) the equivalent to the difference between:
import x
and:
from x import *
.NET assemblies and Java jars/Java 9 modules/OSGI modules provide
some of the extra functionality that Python modules has over
pure namespaces.

I guess there are two approaches to naming:

shorter is better -> less typing and smaller files

 There is another useful approach, and that is
      import «long-winded-name» as «short-name»
 Python supports this, too.
 Java, which needs it more, doesn’t.

Lot of languages support that feature.
C++, C#, VB.NET, Kotlin, Groovy, Scala etc..
But Java does not.
