    Rating = PlayListRatings[i]
    i = i + 1 #Try uncommenting the line and comment the previous i = i + 1, and see the difference, 10 value will get printed twice because when the loop starts it will print Rating and then with PlayListRatings[0], it will again assign the value 10 to Ratings. 
    
    
    
# Write a while loop to copy the strings 'orange' of the list squares to the list new_squares. Stop and exit the loop if the value on the list is not 'orange':

    new_squares.append(squares[i])
