You open a platform session using the default value of the signon_control parameter (signon_control=True).
In future library version v2.0, this default will be changed to False.
If you want to keep the same behavior as today, you will need to set the signon_control parameter to True either in the library configuration file
({'sessions':{'platform':{'your_session_name':{'signon_control':true}}}}) or in your code where you create the Platform Session.
These alternative options are already supported in the current version of the library.

You can use the Refinitiv Data Library for Python to retrieve the North American Industry Classification System (NAICS) codes associated with a company. It is a standard used by US statistical agencies to classify business establishments for economic analysis.
To do acquire the data, pass a company’s Refinitiv Instrument Code to the get_data method with a request for NAICS related fields.
Here’s a query for Thomson Reuters:
rd.get_data(
'TRI.N',
fields=[
# Basic stuff
"TR.CommonName",
"TR.TickerSymbol",
# NAICS codes
"TR.NAICSSectorCode",
"TR.NAICSSector",
"TR.NAICSSubsectorCode",
"TR.NAICSSubsector",
"TR.NAICSIndustryGroupCode",
"TR.NAICSIndustryGroup",
"TR.NAICSIndustryCode",
"TR.NAICSIndustry",
"TR.NAICSActivityCode",
"TR.NAICSActivity",
]
)
Session is not opened. Can't send any request
