The python slicing syntax is: stringvar[start:end]

If start > end then you always get an empty string (unless end is negativ=
e=20
which means "from the right").

What is it you are trying to slice out of the URL, the name of the parent=
 or=20
something? Quite frankly the concept you have presented scares me ;^) The=
re=20
is likely a better way that doesn't involve slicing the URL.

Please let us know what you are trying to do (rather than just throw brok=
en=20
code at us) and maybe we can help you better.
