Little Python snippet to automatically mirror any console print to a backup log file

mirror_console_to_file.py

from datetime import datetime

class SubLogger(object):
    def __init__(self, name, source, logger):
        self.name = name
        self.source = source
        self.logger = logger

    def write(self, message):
        self.logger.log(self.name, message, self.source)
    def flush(self):
        self.logger.flush(self.source)

class Logger(object):
    def __init__(self, file):
        self.file = open(file, "w")
        self.file.write(f'{datetime.now()} Starting log...\n')
    def __del__(self):
        self.file.write(f'{datetime.now()} Log ended!\n')
        self.file.flush()
        self.file.close()

    def log(self, name, message, backup):
        self.file.write(message)
        backup.write(message)
    def flush(self, backup):
        self.file.flush()
        backup.flush()

    logger = Logger(file)
    sys.stdout = SubLogger('stdout', sys.stdout, logger)
    sys.stderr = SubLogger('stderr', sys.stderr, logger)
