Python Pandas - 建立兩個 Index 物件的並集
要製作兩個 Index 物件的並集,在 Pandas 中使用 index1.union(index2) 方法。首先,匯入所需的庫 −
import pandas as pd
建立兩個 Pandas 索引 −
index1 = pd.Index([10, 20, 30, 40, 50]) index2 = pd.Index([80, 65, 60, 70, 55])
顯示 Pandas index1 和 index2 −
print("Pandas Index1...\n",index1)
print("Pandas Index2...\n",index2)執行並集 −
res = index1.union(index2)
示例
以下為程式碼 −
import pandas as pd
# Creating two Pandas index
index1 = pd.Index([10, 20, 30, 40, 50])
index2 = pd.Index([80, 65, 60, 70, 55])
# Display the Pandas index1 and index2
print("Pandas Index1...\n",index1)
print("Pandas Index2...\n",index2)
# Return the number of elements in Index1 and Index2
print("\nNumber of elements in index1...\n",index1.size)
print("\nNumber of elements in index2...\n",index2.size)
# Perform union
res = index1.union(index2)
# Union of both the indexes
print("\nThe index1 and index2 Union...\n",res)輸出
將產生以下輸出 −
Pandas Index1... Int64Index([10, 20, 30, 40, 50], dtype='int64') Pandas Index2... Int64Index([80, 65, 60, 70, 55], dtype='int64') Number of elements in index1... 5 Number of elements in index2... 5 The index1 and index2 Union... Int64Index([10, 20, 30, 40, 50, 55, 60, 65, 70, 80], dtype='int64')
