I wrote a python project as my linux server. Currently all the logs are printed on terminal. I want to save the logs into log files in a directory named "logs". And I want the log files to group by day and the file name is the date.
assistant:
To achieve this, you can use the logging library in Python. This library is a built-in package, so you don't need to install anything. We will configure the logging package to create log files in the 'logs' directory with the date in the filenames.
Here's a step-by-step solution:
Import required libraries:
import os
import logging
from logging.handlers import TimedRotatingFileHandler
from datetime import datetime
Create a directory named 'logs' if it doesn't exist:
log_dir = "logs"
if not os.path.exists(log_dir):
os.makedirs(log_dir)
Set up a function to configure the logging mechanism:
def setup_logging():
# Create a custom logger
logger = logging.getLogger("my_logger")
logger.setLevel(logging.DEBUG)
# Create a log file with the current date
current_date = datetime.now().strftime('%Y-%m-%d')
log_file = os.path.join(log_dir, f'{current_date}.log')
# Create a file handler that rotates the log file daily
file_handler = TimedRotatingFileHandler(log_file, when = "midnight", interval = 1, encoding='utf-8'))
file_handler.suffix = "%Y-%m-%d.log"
file_handler.setLevel(logging.DEBUG)
# Create a console handler
console_handler = logging.StreamHandler()
console_handler.setLevel(logging.DEBUG)
# Create a formatter
formatter = logging.Formatter('%(asctime)s - %(name)s - %(levelname)s - %(message)s')
file_handler.setFormatter(formatter)
console_handler.setFormatter(formatter)
# Add the file handler and console handler to the logger
logger.addHandler(file_handler)
logger.addHandler(console_handler)
return logger
Now use the logger to log messages:
logger = setup_logging()
logger.debug("This is a debug message.")
logger.info("This is an info message.")
logger.warning("This is a warning message.")
logger.error("This is an error message.")
logger.critical("This is a critical message.")
When you run the Python script, it will create log files with the current date as their names in the 'logs' directory. The log files will also display on the console.
You can also configure the logging format, level, and rotation settings as needed.

If I have multiple python files in my project and I want the logic to take effect for all the python files, where shall I put the logic into?
assistant:
You can create a separate Python file for the logging configuration, and then import and use the logger in each Python file you create, following the DRY (Don't Repeat Yourself) principle.
Follow these steps:
Create a new Python file called logger_config.py in your project's root directory.
In logger_config.py, place the code for the logging configuration:

Follow these steps:
Create a new Python file called
logger_config.py
in your project's root directory.In
logger_config.py
, place the code for the logging configuration:setup_logging()
function fromlogger_config.py
and create a logger instance:This way, you can use the same logging configuration across all your Python files by just importing and calling the
setup_logging()
function.If you want to customize the logger name for each file, you can modify the
setup_logging
function to accept a name parameter:And then, when calling it in other modules, you can pass a custom name:
