Does anyone know why this code isnt working as intended?

Python Help

import random

options = ["goat", "goat", "car"]

def monty_hall_stick(number_of_goes):
    games_played = 0
    wins = 0
    while games_played < number_of_goes:
        random.shuffle(options)
        guess = random.choice(options)
        if guess == "car":
            wins = wins + 1
        games_played = games_played + 1
    decimal = wins / number_of_goes
    percentage = decimal * 100
    percentage = percentage // 1
    print("The win percentage of sticking with your first choice is", percentage, "%")
    

def monty_hall_switch(number_of_goes):
    games_played = 0
    wins = 0
    while games_played < number_of_goes:
        options = ["goat", "goat", "car"]
        random.shuffle(options)
        guess = random.choice(options)
        guess = options.index(guess)
        del options[guess]
        options.remove("goat")
        guess = random.choice(options)
        if guess == "car":
            wins = wins + 1
        games_played = games_played + 1
    decimal = wins / number_of_goes
    percentage = decimal * 100
    percentage = percentage // 1
    print("The win percentage of swapping after revealed goat is", percentage, "%")
    
print("Welcome to the Monty Hall problem simulator")
method = input("Would you like to use the Switch method (Sw) or the Stick method (St)?: ")
method = method.lower
number_of_goes = int(input("How many games should the simulator run?: "))



if method == "sw" or "switch":
    monty_hall_switch(number_of_goes)
elif method == "st" or "stick":
    monty_hall_stick(number_of_goes)
else:
    print("Thats not a valid method. Try again")

Because of this line:

Another thing to be aware of:

This…
method = method.lower
sound be…
method = method.lower()

Better still…
method = input("Would you like to use the Switch method (Sw) or the Stick method (St)?: ").lower()

Also (not that it makes too much of a difference here) when you have code such as if method == "sw" or "switch": personally, I’d use if method in ("sw", "switch")
That way it’s an easy code edit to add more options to the tuple should more options be needed.
