Python: confusions with urljoin

python, python-3.x

Solution

The best way (for me) to think of this is the first argument, `base` is like the page you are on in your browser. The second argument `url` is the href of an anchor on that page. The result is the final url to which you will be directed should you click.

>>> urljoin('some', 'thing')
'thing'

This one makes sense given my description. Though one would hope base includes a scheme and domain.

>>> urljoin('http://some', 'thing')
'http://some/thing'

If you are on a vhost some, and there is an anchor like `<a href='thing'>Foo</a>` then the link will take you to `http://some/thing`

>>> urljoin('http://some/more', 'thing')
'http://some/thing'

We are on `some/more` here, so a relative link of `thing` will take us to `/some/thing`

>>> urljoin('http://some/more/', 'thing') # just a tad / after 'more'
'http://some/more/thing'

Here, we aren't on `some/more`, we are on `some/more/` which is different. Now, our relative link will take us to `some/more/thing`

>>> urljoin('http://some/more/', '/thing')
'http://some/thing'

And lastly. If on `some/more/` and the href is to `/thing`, you will be linked to `some/thing`.
