Python to specify which module to import from if there are duplicate module names?

Question

dirA/
    A.py
    B.py
dirB/
    B.py

A.py
import B

# do blah

I want A to import B.

How do i specify A to import B from dirB instead of dirA since both dirs have B.py?

What do you mean by "I want A to import B". There are two Bs. Which B do you want A to import? Why do you have `B.py` in `dirA` if you don't want A to import it? — BrenBarn, Feb 05 '15 at 20:10
exactly. thats the problem since there are two. Its a version control thing in my software. there are cases where A (which is a wrapper) needs import from previous version B.py located in different tree in the file system — ealeon, Feb 05 '15 at 20:11
I think you should explain your actual situation. You probably need to rethink your strategy for this problem. Trying to import one of multiple identically-named files in separate directories that are not packages is going to lead to very confusing code. — BrenBarn, Feb 05 '15 at 20:18

I think what you're asking for is how to load a module directly from a directory.

import imp

moduleB = imp.load_source('moduleB', '/ModuleBPath/B.py')
moduleB.MyClass()

i think this is assumping that dirA and dirB has __init__.py. what if they dont? – ealeon Feb 05 '15 at 20:15

You could try such variant:

from ..dirB import B
