How To Write Logs To A File With Python?
Using Basic Configuration
You can use basic config. If you configure the attribute filename
, logs will
be automatically saved to the file you specify. You can also configure the
attribute filemode
. Setting the value to w
will overwrite the file after
every entry.
import logging
logging.basicConfig(filename="logs.log", filemode="w", format="%(name)s -> %(levelname)s: %(message)s")
logging.warning("warning")
OUTPUT
root -> WARNING: warning
Using Provided Classes
You can also use the provided classes - loggers and handlers:
logger = logging.getLogger(__name__)
FileOutputHandler = logging.FileHandler('logs.log')
logger.addHandler(FileOutputHandler)
logger.warning("Warning.")
You will create a logger and a handler. When creating a handler, assign the
class FileHandler
and a file name as an attribute. Then set the handler to a
logger:
