Write an application inpython that allows a user to play the game bulls and cows against a computer. the game works as follows: the computer chooses a 4-digit number in secret. the digits must all be different. the user then guesses the number and the computer provides the number of matching digits. if the matching digit is in the right position it is a "bull", if it is on a different position it is a "cow". for example: computer chooses: 3691 user guesses: 1649 computer answers: 1 bull and 2 cows if the user guesses a number with repeat digits that is partially correct the rule is that a correct digit can only count once and bulls count before cows. so for example computer chooses: 3691 user guesses: 4211 computer answers: 1 bull and 0 cows your program should report the number of attempts the user needed to guess the number. hint: you may find it easier to store these numbers as strings or in lists rather than as plain integers.
