三个箭头（“>>”）符号是什么意思？ [英] What do the three arrow (">>>") signs mean?

问题描述

所以这可能是一个愚蠢的问题，但是我现在已经搜索了很长时间，即使我经常在源代码中看到它们，我也无法弄清楚它们的作用。

So this is probably a dumb question, but I have now been searching for quite some time, and I haven't been able to figure out what they do even though I see them often in source-codes.

推荐答案

您不会在源代码中看到它，它很可能是文档。它表示一个交互式会话，并且在解释器中键入的内容都带有此标记。输出显示时没有箭头。

You won't see it in source code, it's probably documentation. It indicates an interactive session, and things typed into the 'interpreter' are marked with this. Output is shown without the arrows.

实际上， Python文档通常在示例代码的右上角有一个>>> 按钮，以便隐藏箭头（并输出），以便您可以复制并粘贴代码。

In fact, the python documentation often has a button >>>at the top right of example code to be able to hide the arrows (and output) so that you can copy and paste the code.
