Question

I want to learn the skill to log in websites with Python, so I copy other's code then try to understand them. I've write several web crawls which don't need to post data to the websites by myself. But this time, when I try to learn crawls that need post data, Python doesn't work.

It's the wrong message from Windows Command Line:

C:\Python26\lib\cookielib.py:1579: UserWarning: cookielib bug!
Traceback (most recent call last):
    File "C:\Python26\lib\cookielib.py", line 1577, in make_cookies
      parse_ns_headers(ns_hdrs), request)
    File "C:\Python26\lib\cookielib.py", line 1534, in _cookies_from_attrs_set
      cookie = self._cookie_from_cookie_tuple(tup, request)
    File "C:\Python26\lib\cookielib.py", line 1527, in _cookie_from_cookie_tuple
      rest)
    File "C:\Python26\lib\cookielib.py", line 764, in __init__
      self._rest = copy.copy(rest)
AttributeError: 'module' object has no attribute 'copy'

    _warn_unhandled_exception()

Actually, I have tried to use Python2.7.6 and Python2.6 and refresh 2.7.6 for times.

The code that I copied is from http://www.oschina.net/code/snippet_1253232_26503. This code is right because lots of people run this code .

I provide an account: Email='13018015260'(Also can be telephone number in this site),password='qwerty'

The code is not the problem, but the Python itself. Once I use cookielib in code, Python on my computer doesn't work!

Sorry for my poor English, I want to know the answer, because I even can't find similar problems in Google!

Solution

Make sure that you do not have your own copy.py or copy.pyc in python path.

You can check that using following command in python interactive shell.

python -c "import copy; print(copy.__file__)"

It should print path something like:

c:\python27\lib\copy.pyc

If the above command print something that does not reference the file in standard library path, renamed the file (copy.py), and make sure you delete copy.pyc file.
