I dont want any logger prints in my terminal. I have separate log file where I will dump all the logger messages.

So now if I do

logger.exception('error')

The message will be shown in terminal which I dont want.

I assume I need to change something here in my code.

stream_handler = logging.StreamHandler()

stream_handler.setLevel(logging.ERROR)

Edited:

According to that I need to set

stream_handler.setLevel(logging.CRITICAL)

If I do that in the logger file I am seeing some unnecessary prints. So I want to be in

stream_handler.setLevel(logging.ERROR)

And not want any prints in the terminal. So can somebody help ?

Are you using `logger.exception('error')` to log an exception? From the [documentation](https://docs.python.org/3/library/logging.html#logging.Logger.exception) `exception()` logs at the `error` level. Which is the level you've set your `stream_handler` – Marcelo Paco Mar 29 '23 at 06:35
@MarceloPaco ```stream_handler = logging.StreamHandler()``` This is how its initialized. So by default If stream is not specified, sys.stderr is used. – bad_coder9042093 Mar 29 '23 at 06:46
Hmm... I found the answer thanks @Ake. – bad_coder9042093 Mar 29 '23 at 06:58
so the answer is ```handler.setLevel(logging.CRITICAL)``` . – bad_coder9042093 Mar 29 '23 at 07:00
