python基础===用9种方式生成新的对象

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

 

 

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·
