Logging a function

[snippsat]

So a setup like this,we get a lot of info.

import my_log

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

if __name__ == '__main__':
   my_log.logger.info('Start')
   value = add(33, 50)
   my_log.logger.debug(value)
   my_log.logger.info('Finish')
   print(value)

After two run in logg file,second run with add(5, '50').

Output:
2017-04-17 13:05:53,512 - my_log - INFO - Start
2017-04-17 13:05:53,513 - my_log - DEBUG - 83
2017-04-17 13:05:53,513 - my_log - INFO - Finish
2017-04-17 13:06:36,155 - my_log - INFO - Start

Traceback (most recent call last):
  File "log6.py", line 5, in add
    return(x + y)

2017-04-17 13:06:36,156 - my_log - INFO - Finish

I import my_log where the setup is.

# create a logging format
