Python - 检查 Pandas 索引是否包含分类数据

要检查Pandas索引是否包含分类数据，请使用Pandas中的方法。首先，导入所需的库——index.is_categorical()

import pandas as pd

使用以下方法创建类型设置为类别的Pandas索引astype()-

index = pd.Index(["Electronics","Accessories","Furniture"]).astype("category")

显示熊猫指数-

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

检查索引是否包含分类数据-

print("\nDoes Index holds categorical data?\n",index.is_categorical())

示例

以下是代码-

import pandas as pd #创建Pandas索引 index = pd.Index(["Electronics","Accessories","Furniture"]).astype("category") #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...\n",index.dtype) #检查索引是否包含分类数据 print("\nDoes Index holds categorical data?\n",index.is_categorical())输出结果

这将产生以下输出-

Pandas Index... CategoricalIndex([Electronics, Accessories, Furniture], categories=[Accessories, Electronics, Furniture], ordered=False, dtype=category) Number of elements in the index... 3 The dtype... category Does Index holds categorical data? True
