  • 《利用python进行数据分析》NumPy基础:数组和矢量计算 学习笔记

    一.有关NumPy

    (一)官方解释

    NumPy is the fundamental package for scientific computing with Python. It contains among other things:

    • a powerful N-dimensional array object
    • sophisticated (broadcasting) functions
    • tools for integrating C/C++ and Fortran code
    • useful linear algebra, Fourier transform, and random number capabilities

    Besides its obvious scientific uses, NumPy can also be used as an efficient multi-dimensional container of generic data. Arbitrary data-types can be defined. This allows NumPy to seamlessly and speedily integrate with a wide variety of databases.

    (二)书本介绍

    NumPy(Numerical Python)是高性能科学计算数据分析的基础包。

    (二)NumPy的ndarray:一种多维数组对象

    书本p83相关补充:

    shape:表示各维度大小

    dtype:用于说明数组数据类型
