The method of separating Python code and annotations _python

Below for you to share a Python code and comments separate method, has a good reference value, I hope to help you. Come and see it together.

Python notation differs from C language, C + +, Java

In the Python language, use ' # ' to annotate, followed by three quotes

The program in this article will separate the comments in Python with the ' # ' three quotes, and of course you can merge them back again.

There's a need for a little buddy to watch.

This program is known to issue, can not handle the space after the "#" in the beginning of the comment, all the comment lines, must be shelf written

If you have time, then write a full version again.
