This function will do what you want:
"""
def importhack(name):
    mod = __import__(name)
    g = globals()
    for var in dir(mod):
        if var[0] != '_':
            g[var] = getattr(mod, var)
"""
Whether or not you actually want to do this is another question.  I
would guess that it is probably a bad idea, but could be useful
anyway.
