Question

所以这是我的问题。我在python 3.3.2中创建了一个电话簿，我需要知道如何调用单独的函数。这是我的代码：

details = {"Toby": "123", "James": "234", "Paul": "345"}

print("Welcome To The Telephone Directory.\n")

print("To search out specific details, please type Search.\n To add a new person to the Directory, type Add.\n To change someone's details, please type Edit.")

search = input();

if(input() == search.strip() in "search Search SEARCH".split()):

    def search():

        print("Please enter the name of the customer.")
        customer = input()
        print("Number:" ,details.get(customer))
        if(customer not in details):
             print("I'm sorry, but the person you defined is not in the directory.")


flag = True
while flag:
    search()
    flag = input("Would you like to look up another person? [Y/N]") == "y"

if(input() == add.strip() in "add Add ADD".split()):
    def add():

        print("Please enter the name of the new entry.")
        name = input()
        print("Now enter the entry's phone number.")
        telNumber = input()
        details[name] = telNumber
        print("You have succesfully added a new entry:\n",name,"\n",telNumber)

所以我需要知道如何从一开始就调用Add函数。

有什么想法吗？

您正在定义从未实际调用的If语句中的函数

你想要这样的东西：

def do_definition(x): #defining your function, before you call it
    print(x)

y = 'foo'
if statement:
    do_definition(y) # this is actually calling the function

通常在您开始时，您希望首先在顶部定义您的功能，然后在其他地方调用它们

我认为你可能想检查你的语法。

当你正在制作search = input()时（你在btw之后不需要一个半冒号），然后你再来电话search()这在技术上意味着你正在调用input()()这很奇怪。

另外，如果您将def search():内容移出if语句，则表示您在代码中使用了另一个名为search的变量，这会导致生活混乱。
