Made trickier by the similar yet different behaviour of urlparse.urljoin.

 >>> import urlparse
 >>> urlparse.urljoin("hello", "/world")
 '/world'
 >>> urlparse.urljoin("hello", "slash/world")
 'slash/world'
 >>> urlparse.urljoin("hello", "slash//world")
 'slash//world'
 >>>

It does not make sense to me that these should be different.
