This is a nice, concise alternative to the more cumbersome s[n:len(s)]: For any string s and any integer n (0 n len(s)), s[:n] + s[n:] will be equal to s: Omitting both indices returns the original string, in its entirety. For now, the goal is to present some of the more commonly used built-in methods Python supports for operating on string objects. 36%. Why does Mister Mxyzptlk need to have a weakness in the comics? Not the answer you're looking for?

This shifted index when passed to strs [new_index] yields the desired shifted character. s.splitlines() splits s up into lines and returns them in a list. Difficulties with estimation of epsilon-delta limit proof. In Python, indexing syntax can be used as a substitute for the slice object.
