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
