Have you ever faced issues while debugging your Python application because of insufficient or missing logs? Or have you wished to keep track of critical events happening within your app but don’t know where to start? If yes, then this post is just for you! We will explore the world of file logging in Python and learn how to add it to our applications easily.
By the end, you will be able to create customized log files that can help monitor, troubleshoot, and improve your apps’ performance.
What is File Logging?
File logging refers to writing application-related information into external files instead of relying solely on console outputs. This approach provides several benefits such as:
- Storing logs even when the terminal isn’t open or visible.
- Simplified searching through historical data using text editors or specialized tools.
- Separating important events from regular program output.
Python offers built-in support for file logging via its logging module. Let us dive into setting up file logging step by step.
