So the method is to make an element rotate 360 degrees clockwise, very simple.
The from-to often does not meet our daily development needs, so there is this writing

This article mainly explains the group match and the forward match in the regular expression of JavaScript, need to have the basic understanding to the regular, I have been to two kinds of match ambiguity unclear. So summarize here, if there is not, but also hope the big God pointing.1. Group matching:1.1 Capturing group matching ()2.2 Non-capturing group matching (?:)2 forward-looking matches:2.1 Forward forward matching: (? = expression) must be followed by a match.2.2 Reverse forward match: (

The example in this article describes how Python logging the console and file output logs at the same time. Share to everyone for your reference. Specifically as follows:
Python provides a very convenient log module that enables simultaneous output logs to the console and files.
