Python, opposite function urllib.urlencode

Question

How can I convert data after processing urllib.urlencode to dict? urllib.urldecode does not exist.

Answer 1

Python 3 code for Alex's solution:

>>> import urllib.parse
>>> d = {'a':'b', 'c':'d'}
>>> s = urllib.parse.urlencode(d)
>>> s
'a=b&c=d'
>>> d1 = urllib.parse.parse_qs(s)
>>> d1
{'a': ['b'], 'c': ['d']}

The alternative:

>>> sq = urllib.parse.parse_qsl(s)
>>> sq
[('a', 'b'), ('c', 'd')]
>>> dict(sq)
{'a': 'b', 'c': 'd'}

parse_qsl is reversible:

>>> urllib.parse.urlencode(sq)
'a=b&c=d'
