第一种就是创建数组的方式:使用array函数从常规的 list, tuple等格式的数据转创建为ndarray, 默认创建一个新的数组,所创建的数组类型由原序列中的元素类型推导而来。 第二种方法的应用场景是很多时候我们对所创建的数组内的元素未知,但数组的大小已知。针对这种情况,NumPy提供了一些使用占位符创建数组的函数,也就是...

Function field() is needed because '<attr_name>: list = []' would make a list that is shared among all instances. Its 'default_factory' argument can be any callable. For attributes of arbitrary type use 'typing.Any'.Point = make_dataclass('Point', ['x', 'y']) Point = make_data...
