How to access information in custom plugins using python PDK ?

I am using Python PDK to write a custom Plugin for the Kong gateway. Everything setup is done and it's working with the py-hello example. But in the access phase, I want to retrieve all the context and information of the service, consumer. How can I do that. Most of the return value is Table type. Take a look to this example.
```
service = kong.router.get_service()
```

I want to get the service id for example. How can i do that. Thank you

Start with the py-hello example and the access-phase call to kong.router.get_service(); inspect the returned Table value and the Python PDK documentation for its available fields. Document how a plugin can obtain the service id and related service or consumer context, with a runnable example or confirmed reference for the lookup.
