Python - 通过删除多个索引元素来创建新的 Pandas 索引

要通过删除多个索引元素来创建新的Pandas索引，请使用该方法。在其中设置多个索引元素。index.delete()

首先，导入所需的库-

import pandas as pd

创建索引-

index = pd.Index([15, 25, 35, 45, 55, 75, 95])

显示索引-

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

删除第3个位置的多个索引，即索引2和第5个位置，即索引4-

print("\nRemaining Index after deleting multiple index elements...\n", index.delete([2, 4]))

示例

以下是代码-

import pandas as pd #创建索引 index = pd.Index([15, 25, 35, 45, 55, 75, 95]) #显示索引 print("Pandas Index...\n",index) #返回索引中的元素数 print("\nNumber of elements in the index...\n",index.size) #返回基础数据形状的元组 print("\nA tuple of the shape of underlying data...\n",index.shape) #获取数据中的字节 print("\nReturn the bytes...\n",index.nbytes) #获取数据的维度 print("\nReturn the dimensions...\n",index.ndim) #删除第3个位置的多个索引，即索引2和第5个位置，即索引4 print("\nRemaining Index after deleting multiple index elements...\n", index.delete([2, 4]))输出结果

这将产生以下代码-

Pandas Index... Int64Index([15, 25, 35, 45, 55, 75, 95], dtype=int64) Number of elements in the index... 7 A tuple of the shape of underlying data... (7,) Return the bytes... 56 Return the dimensions... 1 Remaining Index after deleting multiple index elements... Int64Index([15, 25, 45, 75, 95], dtype=int64)
