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')
