Question

Fill in needed code to finish Mastermind program in Python 3.7 syntax

Plays the game of Mastermind.
The computer chooses 4 colored pegs (the code) from the colors
Red, Green, Blue, Yellow, Turquoise, Magenta.
There can be more than one of each color, and order is important.

The player guesses a series of 4 colors (the guess).

The computer compares the guess to the code, and tells the player how
many colors in the guess are correct, and how many are in the correct
place in the code. The hint is printed as a 4-character string, where
* means correct color in correct place
o means correct color in incorrect place
- fills out remaining places to make 4

The player is allowed to make 12 guesses. If the player guesses the colors
in the correct order before all 12 guesses are used, the player wins.

Output :

o - here for Y was displayed and it had repeated twice at the beginning that is correct color but incorrect place

Here the string was tested for validity and several characters were correct but in incorrect place
