Logging in Python: Best Practices

Today we're going to talk about something that's about as exciting as watching paint dry, but twice as important: Python logging.

Now, I know what you're thinking. "Nishant, I'd rather stick a fork in my eye than deal with logging." Well, tough noodles, because if you want to be a real programmer - you know, the kind that doesn't spend their weekends hunting for that one bug that's been driving the entire dev team insane - you need to master the art of logging.

You see, logging is like the black box in an airplane. When everything's going smoothly, nobody gives a hoot about it. But the moment your code decides to take a nosedive into the Pacific Ocean of runtime errors, you'll be thanking your lucky stars for every log message you wrote. It's the difference between spending five minutes identifying the problem and spending five days growing a beard while you comb through your entire codebase.

So buckle up. We're about to embark on a magical journey through the land of Python logging. By the end of this article, you'll be logging like a lumberjack on steroids. And who knows? You might even enjoy it. (Okay, that's a stretch, but at least you won't hate it as much.)

Well, as wild as logging can be, which is about as wild as a sloth on sedatives. But hey, you're here to learn, not to party, right? https://last9.io/blog/python-logging-best-practices/
