Python code running from hot key in Ubuntu do nothing

I try to make a simple voice dialing script that should run from hot key in Ubuntu and after recognition return value to clipboard. When I start it from shell, all work as expected. But when I'm trying to use hot key, I got a very strange (on my opinion) behavior that I cannot to understand.For recognition I use online service available through grpc.

So here is a code example:

if __name__ == '__main__':   if is_pid_file_exist:       # here I remove a pid file   else:      # here some code for make a connection and sending data for recognition      # and the next block (with problem) should process response      try:         for r in it:            event_type, alternatives = r.WhichOneof('Event'), None            if event_type == 'final_refinement':               alternatives = [a.text for a in r.final_refinement.normalized_text.alternatives]               recognition = ''.join(alternatives) if len(alternatives[0])>1 else recognition            print(f'type={event_type}, alternatives={alternatives}')         except grpc._channel._Rendezvous as err:            print(f'Error code {err._state.code}, message: {err._state.details}')            raise err

The strange behavior is that all else branch do not work when try-except block uncommented. Even print do not print else.

From hot key start a bash script like this:

#!/bin/bashcd /home/user/script-folder/python3 recognition.py &>> log/recognition.log

So I use shell outputs for logging.

Well, the cherry on the cake: I am new in python.

I tried:

1. comment blocks of code in else branch. So I understand that a mistake around this block of code
2. tear of paths, permissions, environments python version and other - no differences
