How can we modify a Python formula that retrieves Refinitiv data to use an internal data source?

@MylaD20

The LD library for Python has pricing functions, which will take the Service Name of an internal source to get data. See this example on GitHub - https://github.com/LSEG-API-Samples/Example.DataLibrary.Python/blob/lseg-data-examples/Examples/1-Access/EX-1.01.03-PricingStream.ipynb

and the API description for parameters - https://cdn.refinitiv.com/public/lseg-lib-python-doc/2.0.0.2/book/en/sections/content-layer/pricing/pricing-definition/pricing-definition-object.html

from lseg.data.content import pricing

definition = pricing.Definition(
    universe=['EUR=', 'USD='],
    fields=['BID', 'ASK'],
    service="INTERNAL_SOURCE"
)
