Is there a mechanism to comment out large blocks of Python code?

(有没有一种机制可以注释掉大块的Python代码？)

Right now, the only ways I can see of commenting out code are to either start every line with a # , or to enclose the code in triple quotes: """ .

(现在，我可以看到注释代码的唯一方法是使用#开始每一行，或者用三引号括起代码： """ 。)

The problem with these is that inserting # before every line is cumbersome and """ makes the string I want to use as a comment show up in generated documentation.

(这些问题是在每行之前插入#很麻烦， """使得我想用作注释的字符串出现在生成的文档中。)

After reading all comments, the answer seems to be "No".

(阅读完所有评论后，答案似乎是“不”。)

Python does not have such a mechanism.

(Python没有这样的机制。)

Prepend a # to each line to block comment.

(在每行前面添加一个#来阻止评论。)

For more information see PEP 8 .

Most Python IDEs support a mechanism to do the block-commenting-with-pound-signs automatically for you.

(大多数Python IDE都支持一种机制来自动为您执行块注释 - 带符号。)

For example, in IDLE on my machine, it's Alt + 3 and Alt + 4 .

(例如，在我的机器上的IDLE中，它是Alt + 3和Alt + 4 。)

Don't use triple-quotes;

(不要使用三引号;)

as you discovered, this is for documentation strings not block comments, although it has a similar effect.

(正如您所发现的，这是用于文档字符串而不是阻止注释，尽管它具有类似的效果。)

If you're just commenting things out temporarily, this is fine as a temporary measure.

(如果你只是暂时评论一下，这可以作为临时措施。)
