What is the way to restrict the size of log files in Python?

edit

One way to restrict the size of log files in Python is to use the RotatingFileHandler class from the logging module. This class allows you to specify a maximum size for each log file and automatically rotates to a new file once that size is reached.

Here's an example:

import logging
from logging.handlers import RotatingFileHandler

logger = logging.getLogger(__name__)
handler = RotatingFileHandler('logfile.log', maxBytes=1024, backupCount=3)
logger.addHandler(handler)

In this example, the RotatingFileHandler is created with a maximum size of 1024 bytes (1 KB) and a backup count of 3. Once the log file reaches this size, a new file will be created with a new number at the end (i.e. logfile.log.1, logfile.log.2, etc.) and the old log file will be rotated out.
