Modifying "Creating a Python DataPlugin" Example

[JuliaDawkins]

Hopefully this has a simple answer.

I am modifying the Python DataPlugin example from the example, "Creating a Python DataPlugin" example, and would like to populate the tdm_tree with as many channels that are in the file, rather than a fixed number, how can I do this?

The example loads 6 data channels, and my file has a varying number.  

Thanks!

The TDM tree is just a python dictionary where channels is just a python array. 

self.tdm_tree = {
            "author": "National Instruments",
            "description": "Example file",
            "groups": [{
                "name": "Example",
                "description": "The first group",
                "time": datetime.datetime(2020, 2, 11, 15, 31, 59, 342380),
                "channels": [{
                    "name": self.channelNames[0],
                    "description": "",
                    "values": [],
                    "info": "Time in seconds",
                    "type": "DataTypeChnFloat64"
                }]
            }]
        }

So you can work on the structure using standard python mechanisms to extend and modify it.
