No that would mean that a imports b which imports a => circular imports.

Usually it's a cue for bad design.
People solve it by either merging the 2 modules into 1 or defining 'foo' 
in a 3rd module.

You can do also something like :

a.py:

import b
foo = 'I am foo'
b.printThat(foo)

b.py:

def printThat(something):
    print something
