NameError:名称'urllib'未定义"

Question

码:

import networkx as net
from urllib.request import urlopen
def read_lj_friends(g, name):
# fetch the friend-list from LiveJournal
response=urllib.urlopen('http://www.livejournal.com/misc/fdata.bml?user='+name)

错误:

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
NameError: name 'urllib' is not defined

Answer 1

你已经urlopen直接导入了,所以你应该像那样引用它,而不是通过urllib:

response = urlopen('...')

Answer 2

您也可以在 Python 3 中尝试：

from six.moves import urllib

temp_file, _ = urllib.request.urlretrieve(url)

Answer 3

只需放在import urllib代码的顶部即可
