y'rs,
 
I missed the meaning of the ";-)" 
Then didn't read close enough the
"range(len(a)-1,0,-1)"
But your absolutely correct
"Life's-easier-when-you-get-to-select-the-test-case-ly
y'rs"

Unexpectedly the binary search still wins.
Change "range" to "xrange" and it becomes faster.

But the strings have to be the same length.
