i use imp.load_source, so in b.py is :

import imp,os
path = os.path.join(os.path.dirname(__file__), os.path.join('aaa.py'))
ok=imp.load_source('*',path)
print ok.c

it is ok now ,and print 'ccc'

updated3

it is also ok:

import imp,os
imp.load_source('anyname','aaa.py')
from anyname import *
print c

Answer 1

Rename the folder to a different name. A folder with the same name takes precedence.

Answer 2

Use imp.load_module - there you can specify the file directory, overriding the behaviour of import.
