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))
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')
