There is shortest solution for Python3 with use of urllib library (don't know if fastest):

from urllib.parse import urljoin

# output: http://127.0.0.1/asdf/

base_url = urljoin('http://127.0.0.1/asdf/', '.')
# output: http://127.0.0.1/asdf/

base_url = urljoin('http://127.0.0.1/asdf', '.')
# output: http://127.0.0.1/
