I need to write this program in python

the game board is row 4 * column 5

help function (row - 1) * column + (col - 1)

def calculate_str_index(row: int, col: int) -> int: "returns the index in the string representaion of game board with row and column location with number. The str_index represent from A to T return (row 1) * column + (col - 1) def slide_right (square: str, row: int, game_board: str) -> str: THE >>> slide_right (YELLOW_SQUARE, 2, #####Y; 11 square = YELLOW_SQUARE or RED_SQUARE game_board N_ROWS N_COLUMNS The first parameter is the square being added to the game board. The second parameter is a row number and the third parameter is the string representation of a game board. Assume that the square, row number, and game board are valid. slide_right (str, int, str) -> str This function returns a string that is like the original game board, except that: - the square from the first parameter has been slid into the "beginning" (i.e., first column) of the given row number; - the square at the "end" (i.e., last column) has slid off the game board; - the remaining squares have slid to the right
