Python错误类型错误：不支持+：“function”和“function”的操作数类型,python,typeerror,Python,Typeerror,我知道网上有一些关于这个错误的东西，但不管我怎么做，似乎都无法修复它。我昨天刚开始学习Python，是一个绝对的初学者，所以请不要评判我的脚本。这只是一个简单的脚本，想要从一家餐厅接受一位顾客的订单，然后计算出这顿饭的总价格。这很俗气，但我想得到一些帮助。我不能让我的脚本来计算这顿饭的总成本，不管我怎么做，它就是不起作用。你能告诉我我做错了什么，以及如何根据顾客的选择计算餐费总额吗。此外，如果他们选择了菜单上没有的项目，程序将关闭，而不是让他们再试一次。为什么？我将非常感谢你的帮助谢谢 下面是我

下面是我在终端中运行脚本时遇到的成本错误的图片。

这是一张如果我键入菜单上没有的内容时得到的图片。

这是我的剧本

请注意，我从菜单中列出了这些项目，只是为了告诉您它们是什么以及它们的成本

您正在使用局部变量名重新定义函数名

难怪会出现混乱

我知道VisualBasic用于返回值，但在python中不能这样做

只需将局部变量重命名为分配给原始输入结果的变量，就可以了

您不应该将函数命名为与变量相同的函数，即水果函数应如下所示：

def Fruit():
    print("Welcome to The Buttler's Pantery")
    global fruit
    fruit = raw_input("what fruit would you like today?")

    if (fruit == "Apple"):
        Main()
    elif (fruit == "Banana"):
        Main()
    elif (fruit == "Kiwi"):
        Main()
    elif (fruit == "Peach"):
        Main()
    else:
        print("Sorry, but it appears that the item you have ordered is not on the menu")
        Fruit()
还要注意全局性，它使水果在功能水果之外可以访问。如果您要将这些更改应用于所有函数，它应该可以工作

如果您还想让人们再试一次，您可以简单地再次调用该函数，就像在function Fruit中一样

希望这有帮助

您使用函数定义num1、num2。。。值，它将成为局部变量。而你应该把这些变量从函数中去掉。并使用关键字“global”在其他函数中使用这些变量

您好，非常感谢您的回复。我将变量更改为F1，而不是F2，而不是main，依此类推。我也加入了全球术语，但最后我仍然有同样的错误！！！！！请帮忙谢谢，这解决了第二个问题Hi，非常感谢您的回复。我将变量改为F1，而不是F2，而不是main，依此类推。我也加入了全球术语，但最后我仍然有同样的错误！！！！！请帮忙谢谢，这解决了第二个问题
