Python3.x：定义一个类并且调用
1，定一个类Shrjj（其中有属性：name, jjzt,fbsjj,etf,lof,fjlof）：
class Shrjj(object): def __init__(self, name, jjzt,fbsjj,etf,lof,fjlof): self.name = name self.jjzt = jjzt self.fbsjj = fbsjj self.etf = etf self.lof = lof self.fjlof = fjlof def __get__(self, instance, cls): if instance is None: return self else: return instance.__dict__[self.name] def __set__(self, instance, value): instance.__dict__[self.name] = value def __delete__(self, instance): del instance.__dict__[self.name]
2，调用Shrjj类：
# 测试 if __name__ == '__main__': lisrt = [] # 实例化Shrjj类 p = Shrjj('测试','5','4','3','2','1') p2 = Shrjj('测试2','52','4','3','2','12') lisrt.append(p) lisrt.append(p2) # 定义空类（必须带参数，不能写成:p3=Shrjj()） p3 = Shrjj('','','','','','') # 给类属性赋值 p3.name = "cesaldasd" p3.jjzt ="3232.23" lisrt.append(p3) print(lisrt[2].name)
3，运行结果：
cesaldasd
4，可以定义可变参数类（参数个数不固定）：
class People(object): #构造函数，不明确定义参数个数 def __init__(self, *args): self.args = args def sayAge(self): print(str(self.args)) #调用方式 p1 = People() p2 = People('charlie') p3 = People('charlie', 22) p1.sayAge() p2.sayAge() p3.sayAge()
