How to formally insert URL space (%20) using Python? [duplicate]

Question

When a mutli-word search term is entered in ebay, the resultant URL looks something like (for example "demarini cf5 cf12"):

http://www.ebay.com/sch/i.html?_from=R40&_sacat=0&_nkw=demarini%20cf5%20cfc12

I wish to construct this URL in Python so it can be accessed directly. So it's case of concatenating the base URL:

http://www.ebay.com/sch/i.html?_from=R40&_sacat=0&_nkw=

... with the search term. Right now. I am adding the %20 for the spaces explicately thus:

baseUrl = 'http://www.ebay.com/sch/i.html?_from=R40&_sacat=0&_nkw='
searchTerm = 'demarini cf5 cf12'
searchTerm = ('%20').join(searchTerm.split(' '))
finalUrl = baseUrl + searchTerm

What is a more formal way of doing this in Python? I believe the name for this sort of task is URL encoding?

Answer 1

Use urllib library

import urllib
finalurl = baseUrl + urllib.parse.quote(searchterm)

you can use quote_plus() to add + insted of %20 to undo this use

urllib.parse.unquote(str)

In Python 2, use urllib.quote() and urllib.unquote() respectively
