Define a Python key selector function named shooting_pct with 1 parameter. This parameter will be a dictionary which maps strs to ints. The dictionary will have 3 keys: "shot attempts", "shots made", and "minutes". Your function will need to calculate the dictionary's shooting percentage -- the result of their shots made divided by their shot attempts. (This function can be used to help order a list of dictionaries from the dictionary with the lowest shooting percentage to the dictionary with the highest shooting percentage.)
