什么是 Python Whitespace 以及它是如何工作的? [英] What is Python Whitespace and how does it work?

问题描述

我已经在谷歌和这个网站上搜索了一段时间，但我似乎无法找到关于这个主题的直接答案.

I've been searching google and this website for some time now, but I just can't seem to find a straight answer on the subject.

Python 中的空白是什么?我知道这与每行缩进有关，但我不确定如何使用它.它是如何工作的?

What is whitespace in Python? I know it's something to do with indenting with each line, but I'm not sure exactly how to use it. How does it work?

推荐答案

空格用于表示块.在其他语言中，大括号({ 和 })很常见.当您缩进时，它成为上一行的子行.除了缩进，父级后面还有一个冒号.

Whitespace is used to denote blocks. In other languages curly brackets ({ and }) are common. When you indent, it becomes a child of the previous line. In addition to the indentation, the parent also has a colon following it.

im_a_parent:
    im_a_child:
        im_a_grandchild
    im_another_child:
        im_another_grand_child

在我的脑海里，def、if、elif、else、try、except、finally、with、for、while、和 class 都是起始块.结束一个块，你简单的outdent，你会有兄弟姐妹.在上面的im_a_child 和im_another_child 是兄弟.

Off the top of my head, def, if, elif, else, try, except, finally, with, for, while, and class all start blocks. To end a block, you simple outdent, and you will have siblings. In the above im_a_child and im_another_child are siblings.
