[question] how to extract parsed value from the dictionary

[iw5ejm]

def callback(packet): T = packet.get('temperature') print(T)

Running this callback function on a weather packet filtered stream, with AIS.consumer(callback, raw=False)

Why I'm getting only KeyError Exceptions or None value for the temperature (and for all the other key in the dict)? It seems that there is no key in packet.. What am I doing wrong?

thanks, Marco

problem was the nested dictionary for weather data

you have to use something like this to get wx data:

T = packet['weather']['temperature']
print(T)
H = packet['weather']['humidity']
P = packet['weather']['pressure']

Hi @iw5ejm, the packet will be a dict and will have a different structure depending on the message. You will have to check for the weather key, or that format is wx. You can find the various package structure in the docs: https://aprs-python.readthedocs.io/en/latest/parse_formats.html#weather
