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.

Lot of languages support that feature.

C++, C#, VB.NET, Kotlin, Groovy, Scala etc..

But Java does not.
