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
