Python Pandas - 更改索引名称

要更改索引名称，请使用Pandas中的方法。首先，导入所需的库-index.rename()

import pandas as pd

创建熊猫索引-

index = pd.Index([Car,Bike,Airplane, Ship,Truck,Suburban], name =Transport)

显示熊猫指数-

print("Pandas Index...\n",index)

重命名索引-

print("\nRename the index...\n",index.rename(Mode_of_Transport))

示例

以下是代码-

import pandas as pd #创建Pandas索引 index = pd.Index([Car,Bike,Airplane, Ship,Truck,Suburban], name =Transport) #显示Pandas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) #返回数据的dtype print("\nThe dtype object...\n",index.dtype) #重命名索引 print("\nRename the index...\n",index.rename(Mode_of_Transport))输出结果

这将产生以下输出-

Pandas Index... Index([Car, Bike, Airplane, Ship, Truck, Suburban], dtype=object, name=Transport) Number of elements in the index... 6 The dtype object... object Rename the index... Index([Car, Bike, Airplane, Ship, Truck, Suburban], dtype=object, name=Mode_of_Transport)
