I have a problem to install it

Where do I have to put down the .env file? What must be written in there.

When I run python3 listchannels.py I get the following message:

Traceback (most recent call last):
  File "listchannels.py", line 6, in <module>
    import config
  File "/home/arturweiss/tg-relay/config.py", line 3, in <module>
    API_ID = config('1129586')
  File "/home/arturweiss/.local/lib/python3.7/site-packages/decouple.py", line 199, in __call__
    return self.config(*args, **kwargs)
  File "/home/arturweiss/.local/lib/python3.7/site-packages/decouple.py", line 83, in __call__
    return self.get(*args, **kwargs)
  File "/home/arturweiss/.local/lib/python3.7/site-packages/decouple.py", line 68, in get
    raise UndefinedValueError('{} not found. Declare it as envvar or define a default value.'.format(option))
decouple.UndefinedValueError: 1129586 not found. Declare it as envvar or define a default value.

Instead on changing config.py as you did, you should add the config values in your .env like this

API_ID =1129586 ...
