array(data: 'Sequence[object] | AnyArrayLike', dtype: 'Dtype | None' = None, copy: 'bool' = True) -> 'ExtensionArray' Create an array. Parameters --- data : Sequence of objectsThe scalars inside `data` should be instances of thescalar type for `dtype`. It's expected that `data...
Lists are powerful data structures in Python that often represent a series of related attributes. Similarly, dictionaries are used all over Python and are great for structuring information.Sometimes when setting up these data structures, you end up performing the same operation several times. As a ...

创建新类:通过定义一个类,你创建了一个新的对象类型(type of object)。这意味着你可以创建该类的多个实例,每个实例都是类的一个具体化,拥有类定义的属性(attributes)和方法(methods)。 实例化:创建类的实例的过程称为实例化(instances)。每个实例都拥有自己的属性值,但共享类定义的方法。 类实例(Instance): 属...
Vector2d来自示例 11-1,在vector2d_v0.py中实现(示例 11-2)。 该代码基于示例 1-2,除了+和*操作的方法,我们稍后会看到在第十六章中。 我们将添加==方法,因为它对于测试很有用。 到目前为止,Vector2d使用了几个特殊方法来提供 Pythonista 在设计良好的对象中期望的操作。
