Python Pandas - 确定具有相反顺序的两个 Index 对象是否相等


要确定具有相反顺序的两个 Index 对象是否相等,请使用 equals() 方法。

首先,导入必需库 −

import pandas as pd

创建 Pandas index1 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)

检查具有相反顺序的两个 index 对象是否相等 −

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

示例

代码如下 −

import pandas as pd

# Creating Pandas index1 and 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])

# Display the index1 and 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

这将生成以下代码 −

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
