Python如何创建对象，有哪些方法

class Point:

    def __init__(self,x,y):

        self.x = x

        self.y = yimport sysimport copyimport types

point1 = Point(1,2)

point2 = eval("{}({},{})".format("Point",1,2))

point3 = globals()['Point'](1,2)

point4 = locals()["Point"](1,2)

point5 = getattr(sys.modules[__name__],"Point")(1,2)

point6 = copy.deepcopy(point1)

point7 = point1.__class__(1,2)

point8 = type('Point',(Point,),{})(1,2)

point9 = types.new_class('Point',(Point,),{})(1,2)

tpye(name, bases, dict)

name 类名

bases 父类的元组

dict 类的属性方法和值组成的键值对

__class__方法

__class__功能和type()函数一样，都是查看对象所在的类。
