关于urllib的用法

maple412

import urllib
def reporthook(blocks_read,block_size,total_size):
    if not blocks_read:
        print 'Connection opened'
        return
    if total_size < 0:
        print 'Read %d blocks (%d bytes)' % (blocks_read,blocks_read * block_size)
    else:
        amount_read=blocks_read*block_size
        print 'Read %d blocks, or %d/%d' % (blocks_read,amount_read,total_size)

    return

url=''
filename,msg=urllib.urlretrieve(url,reporthook=reporthook)
print 'File:',filename
print 'Headers:'
print msg
错误如下，这是什么原因呢

你的url没有给初始值，给个比方 url='http://www.baidu.com' 之类的。
