Answer 1

Sí, existe urlparse.urljoin o urllib.parse.urljoin para Python 3.

>>> try: from urlparse import urljoin # Python2
... except ImportError: from urllib.parse import urljoin # Python3
...
>>> urljoin("http://www.asite.com/folder/currentpage.html", "anotherpage.html")
''http://www.asite.com/folder/anotherpage.html''
>>> urljoin("http://www.asite.com/folder/currentpage.html", "folder2/anotherpage.html")
''http://www.asite.com/folder/folder2/anotherpage.html''
>>> urljoin("http://www.asite.com/folder/currentpage.html", "/folder3/anotherpage.html")
''http://www.asite.com/folder3/anotherpage.html''
>>> urljoin("http://www.asite.com/folder/currentpage.html", "../finalpage.html")
''http://www.asite.com/finalpage.html''
