Nope, but for totally unrelated reasons (cf Skip's anwer).

OTHO, this is valid:

# foo.py
def bar():
    return "bar"

# A.py
from foo import bar

# B.py
from A import bar
print bar()


FWIW, this is often used in packages __init__.py to hide the package's 
internal organization (or when a module starts to grow too big and has 
to be refactored as a package without breaking client code).
