dtype='int64')] are in the [index]“)在最基本的层面上，Pandas 对象可以认为是 NumPy 结构化数组的增强版本，其中行和列用标签而不是简单的整数索引来标识。我们将在本章的过程中看到，Pandas 在基本数据结构之上提供了许多有用的工具，方法和功能，但几乎所有后续内容都需要了解这些结构是什么。因此，在我们继续之前，让我们介绍这三个基本...

【单选题】Python基本语法仅支持整数、浮点数和复数类型,numpy和pandas库则支持int64/int32/int16/int8等20余种数字类型,如下说法哪个不正确? A、科学计算可能涉及很多数据,对存储和性能有较高要求,因此支持更多种数字类型。 numpy底层是C语言实现,因此,天然支持了多种数据类型。 C、程序员必须精确指定数据类型,因此...
