Python Logging Example

logging_example.py

import logging 

# potential levels to log (hierachy): 
# - DEBUG : everything
# - INFO  : everything except debug
# - WARN  : warn or error 
# - ERROR : only error 
#           e.g. handle error in "try / except" block
#
# CHANGE THIS!!!!
logging.basicConfig(level=logging.DEBUG)

# start info 
logging.info("start program")

# do something you want to debug 
logging.debug("start tricky thing")

# if something weird hits, send warning 
weird_situation = True
if weird_situation: 
    logging.warning("maybe a mistake!")

# finish something you want to debug 
logging.debug("end tricky thing")

# end info
logging.info("end program")

Very nice, thank you!
