Python class

#python一切都是面向对象，不鼓励写类
class test(object):
    a = 1
    def func_1(self):
        pass
    def __init__(self,arg1,arg2):#构造函数
        self.arg1 = arg1 
        self.arg2 = arg2
    
    def __del__(self):#析构函数（不常用，python有自己的垃圾回收机制）
        del self.arg1
        del self.arg2

Small projects pseudo code - small programs
