how to get value from _winrt._winrt_base object

[kfal]

import winrt.windows.devices.sensors as ds

als = ds.LightSensor.get_default()
lux = als.get_current_reading()
x = lux.properties.lookup("{C458F8A7-4AE8-4777-9607-2E9BDD65110A} 62")
print(x) ---> **problem , <_winrt._winrt_base object at 0x0000023045BC4D10> ,  not able to obtain value**

From https://github.com/tpn/winsdk-10/blob/master/Include/10.0.16299.0/shared/sensorsdef.h
lux.illuminance_in_lux is lux.properties.lookup("{C458F8A7-4AE8-4777-9607-2E9BDD65110A} 60")
but we can get float at lux.illuminance_in_lux

Python tip: you can use Python subscript expression instead of calling lookup on a IMapView:

lux.properties["{C458F8A7-4AE8-4777-9607-2E9BDD65110A} 62"]

Since this returns a generic WinRT object type (equivalent of .NET System.Object), you probably need to use the IPropertyValue APIs to get the value. See https://github.com/pywinrt/pywinrt/blob/main/test/test_property_value.py for extensive examples.

Maybe something like this?

import winsdk.windows.devices.sensors as ds
import winsdk.windows.foundation as wf

als = ds.LightSensor.get_default()
lux = als.get_current_reading()
p_x = lux.properties["{C458F8A7-4AE8-4777-9607-2E9BDD65110A} 62"]
x = wf.IPropertyValue._from(p_x).get_single()
print(x)
