logger option , where is the file?

[snippsat]

Look at this post for basic setup.
I would advice to use Loguru
Then all boilerplate code that no one can remember is gone.

from loguru import logger
logger.add("error.log", backtrace=True, diagnose=True)

def add(x, y):
   try:
       return(x + y)
   except Exception as error:
       logger.exception('msg')

if __name__ == '__main__':
    print(add(5, '50')) # Make error

error.log

Output:
2021-04-25 15:25:25.155 | ERROR    | __main__:add:8 - msg
Traceback (most recent call last):

  File "<string>", line 178, in run_nodebug
