WebSep 28, 2024 · The >> operator does a binary bitshift. It moves the binary representation of 1234 on place to the right, discarding the rightmost (least significant) bit. Therefore you code does not result in 3412. You probably want string rotation instead: >>> def rotr (string, n): ... return string [n:] + string [:n] ... >>> rotr ("1234", 2) '3412' http://duoduokou.com/python/40863759515620851957.html
