Python Pandas - 为已创建的索引对象设置索引名称

要为已创建的Index对象设置索引名称，请使用Pandas中的方法。首先，导入所需的库-index.set_names()

import pandas as pd

创建熊猫索引-

index = pd.Index(["Electronics", "Mobile Phones", "Accessories", "Home Decor", "Books"])

显示熊猫指数-

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

设置索引名称-

print("\nSet the index name...\n",index.set_names(Products))

示例

以下是代码-

import pandas as pd #创建Pandas索引 index = pd.Index(["Electronics", "Mobile Phones", "Accessories", "Home Decor", "Books"]) #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) #设置索引名称 print("\nSet the index name...\n",index.set_names(Products))输出结果

这将产生以下输出-

Pandas Index... Index([Electronics, Mobile Phones, Accessories, Home Decor, Books], dtype=object) Number of elements in the index... 5 The dtype object... object Set the index name... Index([Electronics, Mobile Phones, Accessories, Home Decor, Books], dtype=object, name=Products)
