4 tries choice question, one difficulty

[extricate]

Thanks for all the replies. Appreciate it. I've managed to solve it

rainbow = ("red", "orange", "yellow", "green", "blue", "indigo", "violet")
tries = 0

go = True
while go:
    choice = input("Enter rainbow colour: ")
    if choice in rainbow:
        print("Correct")
        go = False
    else:
        tries += 1
        if tries == 4:
            print("Out of tries")
            go = False
        else:
            print("Try again")
