要使用删除的标签列表创建新索引,请使用该方法。在其中传递标签列表。index.drop()
首先,导入所需的库 -
import pandas as pd
创建索引 -
index = pd.Index(['Car','Bike','Truck','Ship','Airplane'])
显示索引 -
print("Pandas Index...\n",index)
包含要删除的标签的列表被传递 -
print("\nUpdated index after deleting labels...\n",index.drop(['Bike', 'Ship']))
以下是代码 -
import pandas as pd # 创建索引 index = pd.Index(['Car','Bike','Truck','Ship','Airplane']) # 显示索引 print("Pandas Index...\n",index) # 返回数据的 dtype print("\nThe dtype object...\n",index.dtype) # 返回基础数据形状的元组 print("\nA tuple of the shape of underlying data...\n",index.shape) # 传递包含要删除的标签的列表 print("\nUpdated index after deleting labels...\n",index.drop(['Bike', 'Ship']))输出结果
这将产生以下代码 -
Pandas Index... Index(['Car', 'Bike', 'Truck', 'Ship', 'Airplane'], dtype='object') The dtype object... object A tuple of the shape of underlying data... (5,) Updated index after deleting labels... Index(['Car', 'Truck', 'Airplane'], dtype='object')
