# Challenge

# Tic tac toe input
# Here's the backstory for this challenge: imagine you're writing a tic-tac-toe game, where the board looks like this:

# 1:  X | O | X
#    -----------
# 2:    |   |  
#    -----------
# 3:  O |   |

#     A   B  C
# The board is represented as a 2D list:

# board = [
#     ["X", "O", "X"],
#     [" ", " ", " "],
#     ["O", " ", " "],
# ]
# Imagine if your user enters "C1" and you need to see if there's an X or O in that cell on the board. 
# To do so, you need to translate from the string "C1" to row 0 and column 2 so that you can check 
# board[row][column].
# Your task is to write a function that can translate from strings of length 2 to a tuple (row, column). 
# Name your function get_row_col; 
# it should take a single parameter which is a string of length 2 consisting of 
# an uppercase letter and a digit.
# For example, calling get_row_col("A3") should return the tuple (2, 0) 
# because A3 corresponds to the row at index 2 and column at index 0in the board.

#My naive solution
def get_row_col(s):
    column_values = {"A": "0", "B": "1", "C": "2"}
    row_values = {"1": "0", "2": "1", "3": "2"}
    a = []
    for x, z in row_values.items():
        for i, y in column_values.items():
            a.append(column_values[s[0]])
            a.append(row_values[s[1]])
    numbers = [ int(x) for x in a ]
    numberslist = [numbers[1], numbers[0]]
    numberstuple = tuple(numberslist)
    return numberstuple

    #Python principles solution
    # def get_row_col(choice):
    # translate = {"A": 0, "B": 1, "C": 2}
    # letter = choice[0]
    # number = choice[1]
    # row = int(number) - 1
    # column = translate[letter]
    # return (row, column)
