Python Pandas - 确定两个相反顺序的 Index 对象是否相等

要确定两个具有相反顺序的Index对象是否相等，请使用equals()方法。

首先，导入所需的库-

import pandas as pd

创建Pandasindex1和index2-

index1 = pd.Index([15, 25, 35, 45, 55, 65, 75, 85, 95]) index2 = pd.Index([95, 85, 75, 65, 55, 45, 35, 25, 15])

显示index1和index2-

print("Pandas Index1...\n",index1) print("Pandas Index2...\n",index2)

检查两个相反顺序的索引对象是否相等-

print("\nAre two Index objects with opposite order equal?" "\n",index1.equals(index2))

示例

以下是代码-

import pandas as pd #创建Pandasindex1和index2 index1 = pd.Index([15, 25, 35, 45, 55, 65, 75, 85, 95]) index2 = pd.Index([95, 85, 75, 65, 55, 45, 35, 25, 15]) #显示index1和index2 print("Pandas Index1...\n",index1) print("Pandas Index2...\n",index2) print("\nAre two Index objects with opposite order equal?" "\n",index1.equals(index2))输出结果

这将产生以下代码-

Pandas Index1... Int64Index([15, 25, 35, 45, 55, 65, 75, 85, 95], dtype=int64) Pandas Index2... Int64Index([95, 85, 75, 65, 55, 45, 35, 25, 15], dtype=int64) Are two Index objects with opposite order equal? False
