Python: how to import part of a namespace

Question

I have a structure that works:

import a.b.c
a.b.c.foo()

and this also works:

from a.b import c
c.foo()

but this does not work:

from a import b.c
b.c.foo()

and does not:

from a import b
b.c.foo()

How can I import to b.c.foo()work?

Answer 1

Just rename it:

from a.b import c as BAR

BAR.foo()

Answer 2

In your package byou need to add ' import c' so that it is always available as part b.

Answer 3

from a import b
from a.b import c
b.c = c

Answer 4

import a.b.c
from a import b
b.c.foo()

The order of the import statements does not matter.
