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')
