Sorting Pm>y m>thon list based on the length of the string
... such that cmp(x, m>y m>) returns -1 if x is less than m>y m>, 0 if x is equal to m>y m>, m>and m> 1 if x is greater than m>y m>.
Of course, m>y m>ou can instead use the kem>y m> parameter:
xs.sort(kem>y m>=lambda s: len(s))
This tells the sort method to order based on whatever the kem>y m> function returns.
