Python Pandas - 使用已删除的标签列表创建新索引
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']))
示例
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')
