The same is the game, the behavior in the process-oriented design scattered in the total number of steps, there is likely to be different drawing version, because the designers often consider the actual situation of a variety of simplification. In object-oriented design, the drawing can only appear in the Checkerboard object, thus guaranteei

Install Python 2 and Python 3 in Windows.

Python BASICS (3) and python BasicsMy life is short. I want to learn Pyhton.
Python is an object-oriented, interpreted computer programming language, invented by Guido van rosum at the end of 1989, the first Public release was released on July 15, 1991. The Python source co

def test(obj) : obj.dump()
Then, input different types of objects to the test () function. I don't need to talk about it later?
C = Child () test (c) # print out childp1 = parent1 () test (P1) # print out parent1★End
Today's topic is to give users who are not familiar with Python a superficial and perceptual understanding of Python's object-oriented features. After talking about Oop, the next post will talk about FP (functi

condition is verified. If a while loop has an else clause, it will always be executed unless your while loop will always go down and will not end!
True and false are called boolean types. You can resolve them to values 1 and 0 respectively. When checking important conditions, Boolean types are very important. They are not true values of 1.
The else block is actually redundant, because you can put the statements in the same block (the same as while) after the while statement, so that the same ef

However, python2.6+ can use the from __future__ import print_function to achieve the same functionality
