http - any python tools to build a complex url with get parameters? -

i wonder if there library allows me build complex urls lot of parameters. following:

request = {   'protocol': "http",   'hostname': "www.example.com",   'port': "80",   'page': "/foo/bar/example.php",   'parameters': {     'foo': "spaced parameter",     'quuz': 42   } }  url = urlbuilder.build(request) 

at point variable url contain following string:

http://www.example.com:80/foo/bar/example.php?foo=spaced%20parameter&quuz=42 

any ideas?

you write tool yourself, example this:

class urlbuilder(object):     def build(self, request):         url = [ request['protocol'],                 '://',                 request['hostname'],                 ':',                 request['port'],                 request['page'],                 ]         pars = request['parameters']         if len(pars):             url.append('?')         parstr = []         key,val in pars.iteritems():             val = str(val)             val = val.replace(' ', '%20')             parstr.append( '{key}={val}'.format(key=key, val=val) )         url.append( '&'.join(parstr) )          return ''.join(url)  request = {   'protocol': "http",   'hostname': "www.example.com",   'port': "80",   'page': "/foo/bar/example.php",   'parameters': {     'foo': "spaced parameter",     'quuz': 42   } }  urlbuilder = urlbuilder() url = urlbuilder.build(request) print url 

output:

http://www.example.com:80/foo/bar/example.php?foo=spaced%20parameter&quuz=42 

of course, piece of code can made more secure. example, now, spaced parameters more 1 space not handled properly. also, might want protect against missing parameters key in request input.
