How to urlencode a query string in Python?

Question

I'm trying to urlencode the string before submitting it.

queryString = 'eventName=' evt.fields["eventName"] '&' 'eventDescription=' evt.fields["eventDescription"];< /pre>

            

Answer 1

Python 2

What you are looking for is urllib.quote_plus:

safe_string = urllib.quote_plus('string_of_characters_like_these:$#@=?%^Q^$')

#Value: 'string_of_characters_like_these%3A%24%23%40%3D%3F%25%5EQ%5E%24'

Python 3

In Python 3, the urllib package has been broken into smaller components. You would use urllib.parse.quote_plus (note the parse submodule)

import urllib.parse
safe_string = urllib.parse.quote_plus(...)

Answer 2

You need to pass the parameters to urlencode() as a map (dict) or sequence of tuples, for example:

>>> import urllib
>>> f = { 'eventName' : 'myEvent', 'eventDescription' : 'cool event'}
>>> urllib.urlencode(f)
'eventName=myEvent&eventDescription=cool+event'

Python 3 or higher

Usingurllib.parse.urlencode:

>>> urllib.parse.urlencode(f)
eventName=myEvent&eventDescription=cool+event

Note that this does not perform url encoding in the usual sense (see the output). To do this, use urllib.parse.quote_plus代码>.
