mqtt message directed to switc-case issue

[misterlisty]

It appears that the message from a mqtt subscription are bytes as when i print them, i get b'PON' for example. I have a switcher statement to execute a function based on the message but it appears to have issues with it being in bytes and i cannot decode it.

def sub_cb(topic, msg):
print("mqtt::",topic,"msg[",msg,"]")
switch_demo(msg.decode('utf-8')) #doesn't recognise decode

def PON():
p_out.value(True)
return "ON"

def POFF():
p_out.value(False)
return "OFF"

def switch_demo(argument):
print("switch_demo::argument[",argument,"]")
switcher = {
'PON': PON,
'POFF': POFF,
}
# Get the function from switcher dictionary
func = switcher.get(argument, lambda: "Invalid month")
# Execute the function
print(func())

@misterlisty
are you sure that your problem is decode? - what is the error message?
For me decode work without problem

>>> a = b'PON'
>>> print(a)
b'PON'
>>> b = a.decode("utf-8")
>>> print(b)
PON
>>>

please look at formating rules of the forum here

e.g. surround your code with triple ``` to make python code format
