Python Pandas - 设置索引的名称

要设置索引的名称，请使用并包含索引名称作为参数。index.set_names()

首先，导入所需的库-

import pandas as pd

创建索引-

index = pd.Index([Car,Bike,Truck,Car,Airplane])

显示索引-

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

设置索引名称-

print("\nIndex name...\n",index.set_names(Vehicle))

示例

以下是代码-

import pandas as pd #创建索引 index = pd.Index([Car,Bike,Truck,Car,Airplane]) #显示索引 print("Pandas Index...\n",index) #返回一个表示索引中数据的数组 print("\nArray...\n",index.values) #设置索引名称 print("\nIndex name...\n",index.set_names(Vehicle))输出结果

这将产生以下代码-

Pandas Index... Index([Car, Bike, Truck, Car, Airplane], dtype=object) Array... [Car Bike Truck Car Airplane] Index name... Index([Car, Bike, Truck, Car, Airplane], dtype=object, name=Vehicle)
