python中把元组转换为namedtuple方法

> c = {"r": 50, "g": 205, "b": 50, "alpha": alpha}
> Color(**c)
> Color(r=50, g=205, b=50, alpha=0)

num_tuple = (1, 2, 3)
string_tuple = ("a", )

> c = {"r": 50, "g": 205, "b": 50, "alpha": alpha}
> Color = namedtuple("Color", c)
> Color(**c)
Color(r=50, g=205, b=50, alpha=0)
