Why canNOT import from a local directory ?

Hi all

 I created a folder named *lib* and put a py file *lib.py* in it.
 In the upper folder I created a py file as:

<CODE>
import lib.lib

def main():
    """
    __doc__
    """
    lib.lib.test()


# ////////////////////////////////////////
if __name__ == "__main__":
    main()


But I got an error :
#.:python main.py
Traceback (most recent call last):
  File "main.py", line 6, in ?
    import lib.lib
ImportError: No module named lib.lib

Why ?
