Python scripts to access LSEG Data Library

Yuji_Takahashi

For one of our clients, I am preparing Python sample scripts to access Real-Time Platform access point of LSEG Data Library (LSEG Data Library for Python | Devportal). I found the following sample Python code on GitHub.
Example.DataLibrary.Python/Examples/4-Session/EX-4.01.01-Sessions.ipynb at lseg-data-examples · LSEG-API-Samples/Example.DataLibrary.Python · GitHub

Can the client access Real-Time Platform access point of LSEG Data Library by using the scripts in Cells 3 and 19 of the sample code?

Cell 3

APP_KEY = 'YOUR APP KEY GOES HERE!'
RDP_LOGIN                   = 'YOUR RDP LOGIN OR MACHINE GOES HERE!'
RDP_PASSWORD                = 'YOUR RDP PASSWORD GOES HERE!'
REALTIME_DISTRIBUTION_SERVICE_HOST      = 'ADS IP'
REALTIME_DISTRIBUTION_SERVICE_USER_NAME = 'DACS USER NAME'

Cell 19

session = ld.session.platform.Definition(
    app_key = APP_KEY, 
    grant = ld.session.platform.GrantPassword(
        username = RDP_LOGIN, 
        password = RDP_PASSWORD
    ),
    deployed_platform_host = REALTIME_DISTRIBUTION_SERVICE_HOST,
    deployed_platform_username = REALTIME_DISTRIBUTION_SERVICE_USER_NAME
).get_session()

Hello @Yuji_Takahashi

The cell 19 code, lets an application connect to both Data Platform (RDP, for snapshot data) and deployed RTDS (for streaming price data).

If the client wants to connect to the deployed RTDS, the cell 18 code is more suitable. The client required the RTDS IP address/Hostname, WebSocket port and DACS username.

• deployed_platform_host: "ADS_IP:WS_PORT"

If the client wants to connect to the RTO/Streaming for Wealth or Data Platform (RDP), uses the cell 17 code.

• RDP_LOGIN = Machine-ID (or email-based user type, but not recommened)
• RDP_PASSWORD = Password
• APP_KEY = APP KEY/Client ID

Please see more detail on the Data Library for Python Quickstart page.
