Question

我收到下面给出的错误消息，并且相同的元素组织在其他程序中工作得很好。我尝试了很多解决方案，但似乎没有用。

html = browse.open(url).read()
File "build\bdist.win32\egg\mechanize\_mechanize.py", line 203, in open
File "build\bdist.win32\egg\mechanize\_mechanize.py", line 230, in _mech_open

File "build\bdist.win32\egg\mechanize\_urllib2_fork.py", line 1062, in do_request_
ValueError: too many values to unpack

以下是代码....请告知。

Answer 1

在你的错误信息中，browse.open（url）.read（）会返回太多的值，但是你只需给一个值来保存它们，所以你得到一个错误，如下：

>>> a = [1,2,3,4]
>>> b,c = a
Traceback (most recent call last):
  File "<string>", line 1, in <module>
ValueError: too many values to unpack (expected 2)

因此，打印出browse.open（url）.read（）的值，并确保值数字与＆＃39; =＆＃39;之前的函数返回长度相匹配。没关系。

Answer 2

browse.open（url）.read（）完成了这个伎俩。感谢@Zoosuck。
