.rfind returns the index if found, -1 if not found.

"World".rfind("World") returns 0, which will be treated as false.

"foo".rfind("World") returns -1, which will be treated as true.

Yes I agree, that code is not very clean.

Hence I added:

print MyString.rfind("World")

Just to figure out if it indeed prints an index.

Index 0 might be of use too, so checking for true/false like I did above 
should not be done.

Consider it incorrect code.

However I didn't care at the time cause I was in a hurry... I knew it was 
dirty but this post correct that and warns people not to write code like I 
did... just in case ! ;)

And also to let you know I am full aware of the shady nature of this code ! 
;) =D
