furl

furl is a small Python library that makes manipulating URLs simple.

Python's standard urllib and urlparse modules provide a number of URL manipulation functions, but using these functions to perform common URL manipulations proves tedious. Furl makes manipulating URLs simple.

Furl is well tested and Unlicensed in the public domain so you can build amazing things.

Query arguments are easy. Really easy.

>>> from furl import furl
>>> f = furl('http://www.google.com/?one=1&two=2')
>>> f.args['three'] = '3'
>>> del f.args['one']
>>> f.url
'http://www.google.com/?two=2&three=3'

Or use furl's inline modification methods.

>>> furl('http://www.google.com/?one=1').add({'two':'2'}).url
'http://www.google.com/?one=1&two=2'

>>> furl('http://www.google.com/?one=1&two=2').set({'three':'3'}).url
'http://www.google.com/?three=3'

>>> furl('http://www.google.com/?one=1&two=2').remove(['one']).url
'http://www.google.com/?two=2'

Encoding is handled for you.

>>> f = furl('http://www.google.com/')
>>> f.path = 'some encoding here'
>>> f.args['and some encoding'] = 'here, too'
>>> f.url
'http://www.google.com/some%20encoding%20here?and+some+encoding=here,+too'

Fragments have a path and a query, too.

>>> f = furl('http://www.google.com/')
>>> f.fragment.path.segments = ['two', 'directories']
>>> f.fragment.args = {'one':'argument'}
>>> f.url
'http://www.google.com/#two/directories?one=argument'

API

Installation

Installing furl with pip is easy.

$ pip install furl

Deprecated methods

f.pathstr, f.querystr, and f.fragmentstr are deprecated in favor of str(f.path), str(f.query), and str(f.fragment). There should be one, and preferably only one, obvious way to serialize URL components to strings.
