Python practiced hand, encapsulated log module, v2

Before the 1th edition is written well, very messy, the main problem is that Python does not support method overloading, want to flexibly create objects, at the time, the workaround is to first chain to selectively set the property (the essence of the method overload is to selectively set the property), then do the instantiation, so that the subsequent creation of the object is very messy.

And then know that Python can default parameters, in disguise to do method overloading

Code: Python3
