Python Pandas - Set index name for an already created Index object
To set index name for an already created Index object, use the index.set_names() method in Pandas. At first, import the required libraries −
import pandas as pd
Creating Pandas index −
index = pd.Index(["Electronics", "Mobile Phones", "Accessories", "Home Decor", "Books"])
Display the Pandas index −
print("Pandas Index...\n",index)
Set the name of index −
print("\nSet the index name...\n",index.set_names('Products'))
Example
Following is the code −
import pandas as pd # Creating Pandas index index = pd.Index(["Electronics", "Mobile Phones", "Accessories", "Home Decor", "Books"]) # Display the Pandas index print("Pandas Index...\n",index) # Return the number of elements in the Index print("\nNumber of elements in the index...\n",index.size) # Return the dtype of the data print("\nThe dtype object...\n",index.dtype) # set the name of index print("\nSet the index name...\n",index.set_names('Products'))
Output
This will produce the following output −
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')
