Python Pandas - 将一组索引选项附加在一起
要将一组索引选项附加到一起，请使用append()Pandas中的方法。首先，导入所需的库-
import pandas as pd
创建熊猫索引-
index1 = pd.Index([10, 20, 30, 40, 50])
显示熊猫指数-
print("Pandas Index...\n",index1)创建要附加的新索引-
index2 = pd.Index([60, 70, 80])
追加新索引-
print("\nAfter appending...\n",index1.append(index2))示例
以下是代码-
import pandas as pd
#创建Pandas索引
index1 = pd.Index([10, 20, 30, 40, 50])
#显示Pandas索引
print("Pandas Index...\n",index1)
#返回索引中的元素数
print("\nNumber of elements in the index...\n",index1.size)
#创建要追加的新索引
index2 = pd.Index([60, 70, 80])
#追加新索引
print("\nAfter appending...\n",index1.append(index2))输出结果这将产生以下输出-
Pandas Index... Int64Index([10, 20, 30, 40, 50], dtype='int64') Number of elements in the index... 5 After appending... Int64Index([10, 20, 30, 40, 50, 60, 70, 80], dtype='int64')
