为什么python为什么使用非常规的三引号进行注释？ [英] Why does python use unconventional triple-quotation marks for comments?

问题描述

为什么python不仅仅使用C / C ++ / Java使用的传统注释风格？

Why didn't python just use the traditional style of comments like C/C++/Java uses:

/**
 * Comment lines 
 * More comment lines
 */

// line comments
// line comments
//

这是否有特定原因，还是只是任意的？

Is there a specific reason for this or is it just arbitrary?

推荐答案

Python不会在注释中使用三引号。注释使用井号（aka磅）：

Python doesn't use triple quotation marks for comments. Comments use the hash (a.k.a. pound) character:

# this is a comment

三引号是文档字符串，并且与注释不同，它实际上是程序的真实字符串：

The triple quote thing is a doc string, and, unlike a comment, is actually available as a real string to the program:

>>> def bla():
...     """Print the answer"""
...     print 42
...
>>> bla.__doc__
'Print the answer'
>>> help(bla)
Help on function bla in module __main__:

bla()
    Print the answer

不严格要求使用三引号，只要它是字符串即可。使用 只是一种约定（并且具有多行的优点）。

It's not strictly required to use triple quotes, as long as it's a string. Using """ is just a convention (and has the advantage of being multiline).
