Python Pandas - 返回由索引选择的值的新索引

要返回由索引选择的值的新索引，请使用Pandas中的方法。首先，导入所需的库——index.take()

import pandas as pd

创建熊猫索引-

index = pd.Index([Electronics,Accessories,Decor, Books, Toys], name =Products)

显示熊猫指数-

print("Pandas Index...\n",index)

获取由索引选择的值的新索引-

print("\nA new Index of the values selected by the indices...\n",index.take([1,2]))

示例

以下是代码-

import pandas as pd #创建Pandas索引 index = pd.Index([Electronics,Accessories,Decor, Books, Toys], name =Products) #显示Pandas索引 print("Pandas Index...\n",index) #返回索引中的元素数 print("\nNumber of elements in the index...\n",index.size) #返回数据的dtype print("\nThe dtype object...\n",index.dtype) #获取索引选择的值的新索引 print("\nA new Index of the values selected by the indices...\n",index.take([1,2]))输出结果

这将产生以下输出-

Pandas Index... Index([Electronics, Accessories, Decor, Books, Toys], dtype=object, name=Products) Number of elements in the index... 5 The dtype object... object A new Index of the values selected by the indices... Index([Accessories, Decor], dtype=object, name=Products)
