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')
