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·
