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.
