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
