# Logging with Python 🪵

Logging can be beneficial if set up correctly. It can help developers to debug if something goes wrong in production.

1️⃣ Here, we are gonna use the logging package in Python.

```python
import logging

logging.basicConfig(level=logging.WARNING)

# 5 levels of severity
logging.debug('Debug message')
logging.info('Info message')
logging.warning('Warning message')
logging.error('Error message')
logging.critical('Critical message')
```

with `basicConfig`, we can set the base logging level that we wanna see in our logs. For example, if level is set to `WARNING`, our logs will display messages for `warning, error & critical` .

2️⃣ A more advanced example of logging config:

```python
logging.basicConfig(
    level=logging.WARNING,
    format="%(asctime)s %(levelname)s %(message)s",
    datefmt="%Y-%m-%d %H:%M:%S",
    filename="logs.log",
)
```

One last note: NEVER PRINT SENSITIVE DATA INTO YOUR LOGS
