Summary: urllib.urlencode doesn't work for output from cgi.parse_qs

Initial Comment:
>>>
urllib.urlencode(cgi.parse_qsl('ext=.jpg&outquality=56'))
'ext=.jpg&outquality=56'
>>>
urllib.urlencode(cgi.parse_qs('ext=.jpg&outquality=56'))
'ext=%5B%27.jpg%27%5D&outquality=%5B%2756%27%5D'

"%5B%27" = "['"

I am only guessing, here, but if you had an object that you 
wanted to embed a representation of in a URL or in HTML 
form data, it would be prudent to call str() on the object and 
let its __str__ method give you a string representation, and 
then you'd percent-encode that. This makes sense for user-
defined classes, where you can define __str__, but not for 
built-in types like an ordinary list, so they give you the doseq 
flag for those situations.

Can you name one web app that you know will take args in the
form of "ext=[27.jpg]"?  Why not do some type inspection to
see what types you are dealing with?  What is the use of
encoding a list in a url using python syntax?

As per the urlencode() API documentation, you are passing in 
sequences, so you need to set the doseq flag.

>>> urllib.urlencode(cgi.parse_qs
('ext=.jpg&outquality=56'),doseq=1)
'ext=.jpg&outquality=56'

I recommend that this bug report be closed as Invalid.
