unused variable is not identified

[Dmitrey Kroshko]

hello,
here is my code snippet
def myFunc(...):
    ....
    msg = f'operation {operation} with macAddress={macAddress} is finished'
    #print(msg)
    return r
so msg must be identified as unused, but there is no proper identification
and information about it.
I have Eric 7 - 26.6
Regards, Dmitrey
