Question

我有一个菜单和一些功能可以继续使用。我的任务是添加更多功能。现在的菜单代码看起来像这样。

def menu():

"""
Display the menu with the options that The Goddamn Batman can do.
"""
print(chr(27) + "[2J" + chr(27) + "[;H")
print(meImage())
print("Hi, I'm The Goddamn Batman. There is nothing I can't do. What can I do you for?")
print("1) Present yourself to The Goddamn Batman.")
print("2) Tell me your age. I'm going to show you a neat trick.")
print("q) Quit.")

问题是print2。我得到了在Cygwin中出现的替代方案，但是当我按下“2”时，我收到错误。功能（不完整）如下所示：

def Age():
"""
Ask the user's age and calculate for how many seconds the user has lived
"""

age = input("How old are you? ")
    if choice == int:
        print ("Ah, %s, that is old." % age)
    result = (input * (int)31 556 926)
    return result
    print("You know what? Your age actually makes ",result, "seconds.")

    else:
        print("That is not a valid choice. Please write a number.")

以前的功能，打印1（名称）和打印q（退出一切），工作正常。例如，print 1看起来像这样：

def myNameIs():
    """
    Read the users name and say hello to The Goddamn Batman.
    """
    name = input("What is your name? ")
    print("\nThe Goddamn Batman says:\n")
    print("Hello %s - you're something special." % name)
    print("What can I do for you?")

为什么打印2（年龄）不会响应？其他的工作正常，但我不能添加更多的功能，让他们工作。希望这有助于其他人学习如何正确地将功能连接到菜单。我只是卡住了。

所以，澄清一下，我的问题是函数def myNameIs():作为Cygwin中的菜单选项响应。函数def Age():没有。我不知道为什么。

在此先感谢，我非常感谢您提供的任何帮助。

编辑：

好的，请求后。这是所有代码。我很抱歉没有提供一个小提琴，但我不知道我可以用于python的任何小提琴。我只找到jsfiddle，它似乎没有任何意义上的python。

您将年数转换为秒数？

1）在python中int()是一个带参数的函数，它不会像(int)31 556 926一样投射值。 2）整数值中没有空格
3）您不能在return语句之后放置代码并期望它运行
4）choice函数中可能无法访问Age。您可以将其添加为参数
5）使用int而不是isinstance(choice, int)检查==，因为您要检查变量的类型，而不是int阶级本身。

def Age():
    """
    Ask the user's age and calculate for how many seconds the user has lived
    """

    age = input("How old are you? ")
    print("Ah, %s, that is old." % age)
    result = int(input) * 31556926  # Fixed this line
    print("You know what? Your age actually makes ",result, "seconds.")
    return result   # Moved this line down

关于您的菜单，您从未执行过您的功能或提示input，但这是您可以做的诀窍

menu_funcs = {'1': myNameIs, '2': Age} # map the options to functions
while True:
    menu()
    choice = input("Enter an option: ")
    if choice == 'q':
        return # exit
    if choice in menu_funcs:
       menu_funcs[val]() # call the function
    else:
       print("That is not a valid choice. You can only choose from the menu.")

Python，将菜单连接到函数
