Python - 在 Pandas 索引中查找应插入元素以保持顺序的索引

要在Pandas索引中查找应该插入元素以保持顺序的索引，请使用该方法。index.searchsorted()

首先，导入所需的库-

import pandas as pd

创建熊猫索引-

index = pd.Index([10, 20, 30, 40, 50])

显示熊猫指数-

print("Pandas Index...\n",index)

Searchsorted：设置要插入的值并获取应放置的确切索引位置-

print("\nThe exact positions where the element should be placed?...\n",index.searchsorted(45))

示例

以下是代码-

import pandas as pd #创建Pandas索引 index = pd.Index([10, 20, 30, 40, 50]) #显示Pandas索引 print("Pandas Index...\n",index) #返回索引中的元素数 print("\nNumber of elements in the index...\n",index.size) #搜索排序 #将值设置为insert并获取应放置的确切索引位置 print("\nThe exact positions where the element should be placed?...\n",index.searchsorted(45))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 The exact positions where the element should be placed?... 4
