📝 Blog post: PyLint message: logging-format-interpolation

👋 Hey there tech enthusiasts! 👨‍💻 Welcome back to our tech blog! Today, we have an interesting question to dive into: PyLint message: logging-format-interpolation. 🤔 If you've come across this warning while using PyLint, you might be wondering why using format() for logger statements is not preferred in Python 3. Let's demystify this warning and find some easy solutions! 🔍💡

📝 Understanding the warning

When you encounter the logging-format-interpolation warning, PyLint alerts you about a specific call format that you're using in your logger statement. It points out that you're using the format() method within the logging function, like this:

logger.debug('message: {}'.format('test'))

🚨 PyLint recommends against this usage and suggests using % formatting instead.

🔍 Why % formatting is preferred for logger statements?

✅ The main reason behind this recommendation is that using % formatting allows the logging function to handle the interpolation of parameters. In simpler terms, % formatting enables the logger to perform the string manipulation for you.

🔄 Let's take a look at an example using % formatting:

logger.debug('message: %s', 'test')

In this example, instead of using format() and specifying the parameter directly inside the logger statement, we pass the parameter as an argument (%s) to the logger function. The logger handles the interpolation and formatting based on the arguments we provide. 🎯

⚡️ Easy solution to fix the warning

If you want to address this PyLint warning and follow the best practice, here's a simple solution:

✅ Replace the format() method with % formatting, pass the parameters as arguments to the logger function, and let the logger handle the string interpolation for you.

🌟 Final Thoughts

🔒 While you have the option to turn off this warning in PyLint, it's essential to understand the reasoning behind it. By using % formatting for logger statements, you ensure cleaner code and comply with the recommended coding conventions, making your code more readable and maintainable. So why not embrace this best practice? 😉💻
