Question

I need help fixing my python3 code. I am trying to get my Monty hall game working correctly. Below is my code. When I run the code it repeats the first question and doesn't work until the 3rd attempt or sometimes more than that. How do I fix this? I also need to be able to make it run 5 times in a row.(like ask the user at least 5 times, so it is re-playable. I added a image of the output to show you.

import random

win = 0
lose = 0
playing = True

while playing:

    door = [1,2,3]
    x = 0
    a = random.choice(door) # Computer chooses the winning door
    b = int(input("Please choose a door (1-3): ")) # User guesses winning door -- .strip() is pointless
    if a == b:
        # If answer = guess, pick one of the remaining doors to open
        door.remove(a)
        x = random.choice(door)
        c = x
        print("You chose door {}".format(b))
        print("I choose door {}".format(c))

        # Tells user which 2 doors are now left:
        door = [1,2,3]
        door.remove(x)
        door.remove(a)
        d = door[0]
        print("You're left with doors {} and {}".format(b,d))
        choice = input("Will you SWITCH to door {}? y/n: ".format(d))

        # Ask user if they want to switch. y = Lose / n = win
        if choice == "y":
            print("Bad luck. You lost. You should have stuck as you already had the right answer.")
            lose += 1
        else:
            print("Yay! You made the right choice!")

Please choose a door (1-3): 2 Please choose a door (1-3): 3 Please choose a door (1-3): 3 You chose door 3 I choose door 2 You're left with doors 3 and 1 Will you SWITCH to door 1? y/n: n Yay! You made the right choice! Please choose a door (1-3):

Answer 1

it's repeating because you programmed it that the program flow will continue only when you guessed the correct door in the first step itself( if a==b )

also there are some logical fallacies..the code with comments

code:

import random

win = 0

lose = 0

playing = True

ct=0

while playing:

if ct>=5:

break

else:

ct+=1

door = [1,2,3]

x = 0

a = random.choice(door) # Computer chooses the winning door

b = int(input("Please choose a door (1-3): ")) # User guesses winning door -- .strip() is pointless

if a==b:

door.remove(a) #if same remove that one

else: #not same remove both

door.remove(a)

door.remove(b)

c = random.choice(door) #the remaining door

print("You chose door {}".format(b))

print("I choose door {}".format(c))

# Tells user which 2 doors are now left:

door = [1,2,3]

door.remove(c)

door.remove(b)

d = door[0]

print("You're left with doors {} and {}".format(b,d))

choice = input("Will you SWITCH to door {}? y/n: ".format(d))

# Ask user if they want to switch. y = Lose / n = win

if choice == "y":

b=d

elif choice=="n":

pass

else: #not valid input

print('not valid input.. exiting')

break

if b!=a: #if user choice not same to picked by computer

print("Bad luck. You lost. You should have stuck as you already had the right answer.")

lose += 1

else:

print("Yay! You made the right choice!")

win+=1

print() #newline

indentation:

note: as you said to run the code for 5 turns i placed the condition for ct == 5, change the condition if you want to change it

output:
