Hi Morne,

One note: if you're looking to see if yolur string contains a certain
substring, be aware that string.find() can also return '0' if it finds
that string at the very beginning.  For example:

###
>>> 'hello world'.find('hello')
0
###

So zero is also a perfectly good value as far as find() is concerned.
It's that '-1' value that you want to watch out for:

###
>>> 'hello world'.find('goodbye')
-1
###

Hope this helps!
