Using Python2.4.5 (don't ask!) I want to parse a query string and get a dict in return. Do I have to do it "manually" like follows?
>>> qs = 'first=1&second=4&third=3'
>>> d = dict([x.split("=") for x in qs.split("&")])
>>> d
{'second': '4', 'third': '3', 'first': '1'}
Didn't find any useful method in urlparse.
You have two options:
>>> cgi.parse_qs(qs)
{'second': ['4'], 'third': ['3'], 'first': ['1']}
or
>>> cgi.parse_qsl(qs)
[('first', '1'), ('second', '4'), ('third', '3')]
The values in the dict returned by cgi.parse_qs() are lists rather than strings, in order to handle the case when the same parameter is specified several times:
>>> qs = 'tags=python&tags=programming'
>>> cgi.parse_qs(qs)
{'tags': ['python', 'programming']}
cgi.parse_qs() are lists instead of strings, the answer is that the same parameter could be specified several times, in which case multiple values have to be returned. This is illustrated by the last example in my answer.
this solves the annoyance:
d = dict(urlparse.parse_qsl( qs ) )
personally i would expect there two be a built in wrapper in urlparse. in most cases i wouldn't mind to discards the redundant parameter if such exist
import urlparse
qs = 'first=1&second=4&third=3&first=0'
print dict(urlparse.parse_qsl(qs))
OR
print urlparse.parse_qs(qs)
