Python - 使用已删除的位置创建新的 Pandas 索引

要删除传递位置的新Pandas索引，请使用该方法。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])

显示索引-

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

删除第3个位置的单个索引，即索引2-

print("\nRemaining Index after deleting an index at location 3rd (index 2)...\n",index.delete(2))

示例

以下是代码-

import pandas as pd #创建索引 index = pd.Index([15, 25, 35, 45, 55]) #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个位置的单个索引，即索引2 print("\nRemaining Index after deleting an index at location 3rd (index 2)...\n",index.delete(2))输出结果

这将产生以下代码-

Pandas Index... Int64Index([15, 25, 35, 45, 55], dtype=int64) Number of elements in the index... 5 A tuple of the shape of underlying data... (5,) Return the bytes... 40 Return the dimensions... 1 Remaining Index after deleting an index at location 3rd (index 2)... Int64Index([15, 25, 45, 55], dtype=int64)
