Now let's test if each color and position in the guess is an exact match.

• Add a Loop with Range. Change the counter to peg_num and the range to 4.
• Use if else to check if the guess at index [peg_num] is equal to the code at index [peg_num].
• If it is equal, add a "black" Circle called marker with coordinates x and y and a diameter of 15.
• If it is equal, Append guess[peg_num] to the colors_matched list.
