How to get real time data from the LightStreamer Server.

Hi,

I am going to get the real time price from the LightStreamer Server using Streaming API.
so I used the following URL: https://ig-markets-api-python-library.readthedocs.io/en/latest/

I have the IG Demo account and tested its sample code above URL support.
But it shows nothing after ----------HIT CR TO UNSUBSCRIBE AND DISCONNECT FROM LIGHTSTREAMER----------- message.

If you want, I can show you source code.

Hope your kindly advices.

Thanks.
