Python: How to import part of a namespace

Question

I have a structure such this works :

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

and this also works :

from a.b import c
c.foo()

but this doesn't work :

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

nor does :

from a import b
b.c.foo()

How can I do the import so that b.c.foo() works?

Answer 1

In your 'b' package, you need to add 'import c' so that it is always accessible as part of b.

Answer 2

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

Answer 3

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

The order of the import statements doesn't matter.

Answer 4

Just rename it:

from a.b import c as BAR

BAR.foo()
