Итак, я не профессионал в python, и я застрял на ошибке, когда я создаю программу, вот код

 # A game that will tell that the news is fake or not.

# Welcome message
print("Want to know that a news is fake or not?nYou are at a right place. Welcome to FakeNewsDetector.orgnAt here we provide the news which is not fake and you can add more news if you want!!nSo are you excited? Let's get startedn")

# User input   print for input
print("What thing you want do?")
print("1: Ask a news is fake or not?n2: Tell a news it is fake or notn")
number = int(input("We will answer your question just enter the number. Press ctrl c anywhere if you want to exit: "))

# if then else



# Appending part
if number == 2:
    number = int(input("What is the number of news you are adding?: "))
    whatAreYouTelling = input("What news you want to say? Not include that the news is false or true: ")
    with open('news.txt', 'a') as f:
        a = f.write(f"n{number}: {whatAreYouTelling}")
    
    trueOrFalse = input("Is the fact true(T) or false(F)?")
    if trueOrFalse == "t" or trueOrFalse == "T":
        fact = True

    elif trueOrFalse == "f" or trueOrFalse == "F":
        fact = False

    else:
        print("Invalid") 



# Reading part
elif number == 1:
    with open('news.txt', 'r') as f:
        a = f.read()
        print(a)

    news = int(input("What news do you want to ask? Enter number: "))

    if news == 1:
        fact = False
        print(f"The news is {fact}.")

    elif news == 2:
        fact = True
        print(f"The news is {fact}")

    elif news > 2:
        print(f"{trueOrFalse}")
else:
    print("Invalid")

# print("nThanks for using our news service. I hope you like itn Created by Anant Guptan Class 7Dn Homework: ATL")
 

И когда я запускаю свой код и добавляю случайное значение, возникает ошибка, подобная этой

Я не очень хороший программист, но, пожалуйста, примите мой фрагмент кода. Я работаю в течение 1 часа и не могу устранить ошибку. Если кто-нибудь решит, я буду очень благодарен. Заранее спасибо

TrueOrFalse область действия ограничена вашим первым if блоком. Чтобы сделать его доступным в вашем втором блоке, вам нужно объявить его вне ваших if операторов, например, установив для него значение False first .
