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
