Using logger

1. Get instance of mwk-logger

from mwk_logger import MwkLogger

log = MwkLogger(name='mwk',
                file='logger.log',
                stream_level='DEBUG',
                file_level='DEBUG',
                time=True)

keyword parameters:

• name - name of the logger, by default = 'mwk',
• file - path to file to log into, by default = 'mwk.log',
• stream_level - logging level for terminal, by default = 'WARNING',
• file_level - logging level for file, by default = None,
• time - if timestamp should be added to terminal log, by default = False,

LEVELS: None - no logging or:
'DEBUG', 'INFO', 'WARNING', 'ERROR', 'CRITICAL'.
If both levels are set to None stream_level is changed to WARNING.
Timestamp is always added to file logs. One can set if timestamp will be added to terminal logs.

2. Logging

log.debug('This is a debug message.')
log.info('This is an info message.')
log.warning('This is a warning message.')
log.error('This is an error message!')
log.critical('This is a critical message!!!')
log.exception('This is an exception message!')

Using decorators

1. @timer - print or log the runtime of the decorated function
2. @f_sig - print or log the signature and the return value of the decorated function

1. Decorator with no arguments

Prints on screen.

from mwk_logger import timer, f_sig

@timer
@f_sig
def function(*args, **kwargs):
    # ... some function ...
    return 'something'

1. Decorator with arguments

Output is logged with provided logger with level = INFO.
!!! keyword logger is obligatory !!!

from mwk_logger import MwkLogger, timer, f_sig

log = MwkLogger()

@timer(logger=log)
@f_sig(logger=log)
def function(*args, **kwargs):
    # ... some function to be logged...
    return 'something'
