我有一个可变的问题，我无法理解你

while True:
    stuff = input("Hey Welcome What Are You Using This For Work, School Or Personal?: ")
    if stuff == "work":
        time.sleep(2)
        print("Authorizing...")
        time.sleep(4)
        print("Authorized! Have Fun")
    if stuff == "school":
        time.sleep(1)
        print("Authorizing...")
        time.sleep(4)

        time.sleep(4)
        print("Authorized! Have Fun!")
    if stuff == "ANONYMOUS04":
        username = input("What Is The Username?: ")
        password = input("What Is The Password?: ")
    if username == "M8TE" and password == "CICADA3007":
        print("Welcome Dear Master Hassan!")
    else:
        print("You Ugly Fool, You Aren't Master!")
        time.sleep(2)

有一个问题，因为用户名没有定义，但我确实定义了它

Answer 1

不，您的username变量没有定义，因为它有错误的缩进。也许你想要这个：

    if stuff == "ANONYMOUS04":
        username = input("What Is The Username?: ")
        password = input("What Is The Password?: ")
        if username == "M8TE" and password == "CICADA3007":
            print("Welcome Dear Master Hassan!")

在这种情况下，定义它是因为它与定义的缩进级别相同
