Python built-in function type () function an interesting usage _python

Today I saw a code of type on the internet and then looked up the document to see that type has three parameters in use.

Http://docs.python.org/2/library/functions.html

Just know that type can detect object types. Then found an interesting usage.

Copy Code code as follows:

def println (self):
A = 1 + 1

Print "%s,%s"% (Self.aa, a)

A = Type (' A ', (), {' AA ': ' Print A ', ' println ': println})

A = A ()

Type (a)
OUT[11]: __main__. A

A.println ()
Print a,2

The first argument is the name of the class, the second tuple is the parent, and the third is the property.

Haha, I think it's funny, although the first parameter in my function is written by self, but if you write a piece of code that uses this method to define the class, and then pay no attention to the specification of the class name, the code becomes very difficult to read.
