Python Pandas - 确定两个 CategoricalIndex 对象是否包含相同的元素

要确定两个CategoricalIndex对象是否包含相同的元素，请使用该equals()方法。首先，导入所需的库-

import pandas as pd

使用“categories”参数设置分类的类别。使用“有序”参数将分类视为有序。创建两个CategoricalIndex对象-

catIndex1 = pd.CategoricalIndex(["p", "q", "r", "s","p", "q", "r", "s"], ordered=True, categories=["p", "q", "r", "s"]) catIndex2 = pd.CategoricalIndex(["p", "q", "r", "s","p", "q", "r", "s"], ordered=True, categories=["p", "q", "r", "s"])

检查两个CategoricalIndex对象是否相等-

print("\nCheck both the CategoricalIndex objects for equality...\n",catIndex1.equals(catIndex2))

示例

以下是代码-

import pandas as pd # Set the categories for the categorical using the "categories" parameter # Treat the categorical as ordered using the "ordered" parameter #创建两个CategoricalIndex对象 catIndex1 = pd.CategoricalIndex(["p", "q", "r", "s","p", "q", "r", "s"], ordered=True, categories=["p", "q", "r", "s"]) catIndex2 = pd.CategoricalIndex(["p", "q", "r", "s","p", "q", "r", "s"], ordered=True, categories=["p", "q", "r", "s"]) #显示CategoricalIndex对象 print("CategoricalIndex1...\n",catIndex1) print("\nCategoricalIndex2...\n",catIndex2) #检查两个CategoricalIndex对象是否相等 print("\nCheck both the CategoricalIndex objects for equality...\n",catIndex1.equals(catIndex2))输出结果

这将产生以下输出-

CategoricalIndex1... CategoricalIndex([p, q, r, s, p, q, r, s], categories=[p, q, r, s], ordered=True, dtype=category) CategoricalIndex2... CategoricalIndex([p, q, r, s, p, q, r, s], categories=[p, q, r, s], ordered=True, dtype=category) Check both the CategoricalIndex objects for equality... True
