I find the answer to my own question. The inspect module have what I
need.

Here is the sample code:

a.py
------------------------------------------------------------------------
import b
print 'hello world from module a'
------------------------------------------------------------------------


b.py
------------------------------------------------------------------------
import inspect

def globals_of_importer():
    """ Return the global namespace of the module that imports this
module. """

    # scan the stack using the inspect module
    stack = inspect.stack()

    # current frame is on the top of the stack
    top_rec = stack[0]
    current_filename = top_rec[1]

    # look for the frame those filename different from current frame
    for frame_rec in stack:
        filename = frame_rec[1]
        if filename != current_filename:
            break
    else:
        return None

    # return the globals from the frame object
    frame = frame_rec[0]
    members = inspect.getmembers(frame)
    for name, value in members:
        if name == 'f_globals':
            return value
    else:
        return None

print globals_of_importer()
------------------------------------------------------------------------
