python: log crash (exception) to file

If you create app for windows you know that user do now like console running on background. But if your app crash you have problem: you d no see error message. Solution is to log it to file. 

 Here is snippet how to implement it:

import os
import getpass
import logging


# log exception to file => for frozen app
logging.basicConfig(
    format="%(asctime)s %(levelname)-8s %(message)s",
    datefmt="%Y-%m-%d %H:%M:%S",
    filename=os.path.basename(sys.argv[0]) + ".log",
)

if hasattr(sys, "frozen"):
    sys.excepthook = exception_hook

def exception_hook(exc_type, exc_value, exc_traceback):
    """Hook for standard exception hook."""
    logging.error("Uncaught exception",
                  exc_info=(exc_type, exc_value, exc_traceback))
    logging.info("User: {}, file: '{}'".format(getpass.getuser()))


def main():
    # log information about user who run app
    logging.getLogger().setLevel(logging.INFO)
    logging.info("User: {}".format(getpass.getuser()))
