Python中9种生成新对象的方法

先定义一个类：

class Point:    def __init__(self, x, y):        self.x = x        self.y = y

下面我们使用9种方法来生成新的对象：

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)

PS: 需要导入sys和types模块
