什么是“”“......”“”“”在一个功能吗？ [英] What does the """...""" in a function do?

问题描述

这三个在函数中是什么意思（在python中），其中包含一条消息？

我们不能用＃来表示这样的报告吗？这是我的一个例子：

What do the three " mean in a function (in python) with a message in it?
Can't we use a # for such a report? Here is an example of what I n:

def make_sandwich(*items):
    """Make a sandwich with the given items."""
    print("\nI'll make you a great sandwich:")
    for item in items:
        print("  ...adding " + item + " to your sandwich.")
    print("Your sandwich is ready!")

所以我的意思是de def下的第一句话（给定项目做一个sandwish 。



谢谢



我尝试过：



试图在谷歌上找到它但没有成功

So what i mean is the first sentence under de def ("""Make a sandwish with the given items.""")

Thank you

What I have tried:

Tried to find it on google but no sucess

推荐答案

这个问题包括2问题，一个关于数据类型，另一个关于该放置的目的。



首先，如解决方案1的答案，这是一个字符串定义。在Python中，你不是克制ned使用单引号创建一个字符串，你可以使用多种方式，这个三重双引号就是其中之一。



就放置而言，该放置使该字符串成为该函数的注释。因此，任何试图使用该功能的人都可以将其视为帮助者评论。为此，请参见评论的正确方法是什么python中的函数？ - 堆栈溢出 [ ^ ]

That is a question that includes 2 questions, one about the data type, and second the purpose of that placement.

First of, as Solution 1 answers, that is a string definition. In Python, you are not restrained to use a single quote to create a string, you can use multiple ways and this triple double quote is one of them.

And as far as the placement is concerned, that placement makes this string a comment for the function. Thus, anyone trying to use the function will be able to see this as a helper comment. For that, see here What is the proper way to comment functions in python? - Stack Overflow[^]

谢谢你们，我是编程的新手:)但我想你注意到了哈哈

Thank you guys, i'm new to programming:) But i think you noticed that haha
