print (main_menu())

好的，所以应该标记错误。那个特定的if / else语句显示为“None”，我尝试了每种方法来修复它。一种方法适用于外部的if / else语句，但不适用于此。

Answer 1

您将输入作为字符串str(input())。然后，您要检查if user_input == 1;测试它是否是一个整数，即使它是一个字符串。相反，尝试使用int(input())转换为整数。此外，行user_input != 1是不必要的，它只相当于在代码中编写True。此外，您在if语句中定义了一个函数，该函数不应该存在：

def main_menu():
    print ("Three Doors Down Figurative Language Game")
    print ("*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*")
    print ("NOTE: TO SELECT, TYPE NUMBER OF OPTION")
    print ("")
    print (" 1) Begin Game")
    print ("")
    print (" 2) Options")
    print ("")
    print ("")
    menu_selection()
def menu_selection():
    valid_answer = ["1","2"]
    user_choice = int(input("Make a choice.."))
    if user_choice in valid_answer:
        if user_choice == 1:
            return("You started the game.")
        else:
            return("Credits to ____, created by ____")
            check_valid(user_choice)
    else:
        print("Please use an actual entry!")
        menu_selection()


def enterText():
    print("ENTER ANSWER!")

print (main_menu())
