That's hardly a PEP-8 compliant line, but I can help out a bit.

return s[0:[(s[0:x]*(len(s)//x+1))[0:len(s)]for x in
range(1,len(s)+1)].index(s)+1]

That's still 83 characters without indentation, but it's close now.

I love the algorithm. Took me a bit of analysis (and inspection of
partial results) to understand what your code's doing, but it's
stupidly elegant and elegantly stupid.
