Legal StudiesPython - 使用 Python 在 Pandas index 中查詢應插入的值（作為陣列傳遞）以維護順序的索引
要查詢應插入的值（作為陣列傳遞）的索引以維護 Pandas index 中的順序，請使用 index.searchsorted() 方法。
首先，匯入所需庫 −
import pandas as pd
建立 Pandas index −
index = pd.Index([10, 20, 30, 40, 50])
顯示 Pandas index −
print("Pandas Index...\n",index)Searchsorted − 將要插入的值設為陣列並獲取應放置這些值的準確索引位置 −
print("\nThe exact positions where the values should be placed?...\n",index.searchsorted([35, 60]))示例
以下是程式碼 −
import pandas as pd
# Creating Pandas index
index = pd.Index([10, 20, 30, 40, 50])
# Display the Pandas index
print("Pandas Index...\n",index)
# Return the number of elements in the Index
print("\nNumber of elements in the index...\n",index.size)
# searchsorted
# set the values to insert like an array and get the exact index positions
# where these values should be placed
print("\nThe exact positions where the values should be placed?...\n",index.searchsorted([35, 60]))輸出
這將生成以下輸出：
Pandas Index... Int64Index([10, 20, 30, 40, 50], dtype='int64') Number of elements in the index... 5 The exact positions where the values should be placed?... [3 5]
