Pandas和NumPy是Python数据科学领域中最基础的两个库,他们都可以读取大量的数据并对数据做计算等处理。有很多的操作他们都能做。只不过一般来说,Pandas的DataFrame是一种“表格”,处理的数据可以是非常复杂的结构,一个DataFrame对象可以包括数值、字符等内容。而NumPy处理的基本对象一般是数值型的数组。 那么,这两个Pyth...

Polars[2]是Pandas最近的转世(用Rust编写,因此速度更快,它不再使用NumPy的引擎,但语法却非常相似,所以学习 Pandas 后对学习 Polars 帮助非常大。 Pandas 图鉴系列文章由四个部分组成: Part 1. Motivation:Pandas图鉴(一):Pandas vs Numpy Part 2. Series and Index:Pandas图鉴(二):Series 和 Index Part 3. D...
首先是准备工作,导入需要使用的库,读取并创建数据表取名为loandata。 importnumpy as np importpandas as pd loandata=pd.DataFrame(pd.read_excel('loan_data.xlsx')) 设置索引字段 在开始提取数据前,先将member_id列设置为索引字段。然后开始提取数据。
