furl

furl is a small Python library that makes parsing and
manipulating URLs easy.

Python’s standard urllib and urlparse modules provide a number of URL
related functions, but using these functions to perform common URL
operations proves tedious. Furl makes parsing and manipulating URLs
easy.

Furl is well tested, Unlicensed in the public domain, and supports
Python 2, Python 3, PyPy2, and PyPy3.

Code time: Paths and query arguments are easy. Really easy.

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

>>> 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'
>>> f.set(host=u'ドメイン.テスト', path=u'джк', query=u'☃=☺')
>>> f.url
'http://xn--eckwd4c7c.xn--zckzah/%D0%B4%D0%B6%D0%BA?%E2%98%83=%E2%98%BA'

Fragments also have a path and a query.

>>> 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'

Or get fancy.

>>> f = furl('http://www.google.com/search?q=query#1')
>>> f.copy().remove(path=True).set(host='taco.com')
...  .join('/pumps.html').add(fragment_path='party').url
'http://taco.com/pumps.html#party'
>>>
>>> f.asdict()
{ 'url': 'http://taco.com/pumps.html#party',
  'scheme': 'http',
  'username': None,
  'password': None,
  'host': 'taco.com',
  'host_encoded': 'taco.com',
  'port': 80,
  'netloc': 'taco.com',
  'origin': 'http://taco.com',
  'path': { 'encoded': '/pumps.html',
            'isabsolute': True,
            'isdir': False,
            'isfile': True,
            'segments': ['pumps.html']},
  'query': { 'encoded': '',
             'params': []},
  'fragment': { 'encoded': 'party',
                'path': { 'encoded': 'party',
                          'isabsolute': False,
                          'isdir': False,
                          'isfile': True,
                          'segments': ['party']},
                'query': { 'encoded': '',
                           'params': []},
                'separator': True}, }
