Question

我目前正在使用python进行娱乐用途，而且这个ATM脚本运行不正常，请帮忙。

def balance():
    balance=7.52
    return balance
    print("Hi, Welcome to the Atm.")
    print("no need for pin numbers, we already know who you are")
    print("please selection one of the options given beneath")
    print("""
            D = Deposit
            W = Withdrawal
            T = Transfer
            B = Balance check
            Q = Quick cash of 20$
            E = Exit
            Please select in the next line.""")

def option():
    option = input("which option would you like?:")
    return option
    input("which option would you like?:")
    if option == "D":
        print("How much would you like to deposit?")
        amount = (int(input("amount:")))
        total = amount + balance

Answer 1

您似乎正在使用Python 2，其中input尝试评估用户输入的内容，就像它是Python语句一样。您应该使用raw_input，而不是。{/ p>

Answer 2

当剧本问你＆＃34;你想要哪个选项？：＆＃34;你必须输入＆＃34; D＆＃34;或者＆＃39; D＆＃39;而不是D导致输入功能，我认为你应该使用raw_input

你还会遇到另一个问题：

total=amount+balance

你必须为呼叫功能添加（）

total=amount+balance()

用这一行：

if option =="D":

原因选项未定义。

option = option()

Answer 3

def balance():
    balance=7.52
    return balance
    print("Hi, Welcome to the Atm.")
    print("no need for pin numbers, we already know who you are")
    print("please selection one of the options given beneath")
    print("""
    D = Deposit
    W = Withdrawal
    T = Transfer
    B = Balance check
    Q = Quick cash of 20$
    E = Exit
    Please select in the next line.   """)
def option():
    option=input("which option would you like?:")
    return option
    input("which option would you like?:")
    if option =="D":
        print("How much would you like to deposit?")
        amount=(int(input("amount:")))
        total=amount+balance

您需要将代码 正确缩进 ，因此它看起来像这样（查找）：
input仅用于Python 3.x. Python 3.x版本的等价物是raw_input，即Python 2.x版本。由于存在混淆，不建议对变量和函数使用相同的名称。最好重命名其中一个。如果您使用的是Python 3.x，则需要修复缩进。试试Python 2.7 Docs或Python 3.x Docs

为什么这不起作用？ “d未定义”
