怎么if __name__ == "__main__":办？

# Threading example
import time, thread

def myfunction(string, sleeptime, lock, *args):
    while True:
        lock.acquire()
        time.sleep(sleeptime)
        lock.release()
        time.sleep(sleeptime)

if __name__ == "__main__":
    lock = thread.allocate_lock()
    thread.start_new_thread(myfunction, ("Thread #: 1", 2, lock))
    thread.start_new_thread(myfunction, ("Thread #: 2", 2, lock))

这是我的代码:

import pickle 

alist = ['here', 'there']
c = open('config.pck', 'w')

pickle.dump(alist, c)

这是我收到的错误:

Traceback (most recent call last):
  File "C:\pickle.py", line 1, in ?
import pickle
  File "C:\pickle.py", line 6, in ?
pickle.dump(alist, c)
AttributeError: 'module' object has no attribute 'dump'

这是怎么回事？我在windows xp上使用python 2.4
