Okay, so I wanted to get a solid logging system going for this MMA (Mixed Martial Arts) project I’ve been messing with. Figured I’d share my little adventure in setting it up – maybe it’ll help someone else out, or maybe future me will thank me for writing this down.
First, I gotta say, I spent a little time just poking around, seeing what other folks were using. You know, the usual “best logging practices” Google search. Lots of fancy stuff out there, but I wanted to keep it simple, at least to start.
The Basic Setup
I decided to start with the built-in Python `logging` module. No need to install anything extra, which is always a plus. Here’s the first thing I did:
import logging
Simple,I use the python default “logging” , and i do not need to install it.
Then, I needed to configure it. I wanted to see the logs in my console AND have them saved to a file. Seemed like a good way to keep track of things.
level=*,
format="%(asctime)s [%(levelname)s] %(message)s",
handlers=[
*("mma_*"),
Let me break down what’s happening there:
level=*: This means I want to see messages that are “INFO” level and above (like “WARNING”, “ERROR”, “CRITICAL”). “DEBUG” messages are too chatty for me right now.
format=…: This is how I want my log messages to look. I wanted the time (%(asctime)s), the severity level (%(levelname)s), and the actual message (%(message)s).
handlers=…: This is where I tell it where to send the logs. FileHandler saves it to a file named “mma_*”, and StreamHandler prints it to my console.
Testing It Out
Now for the fun part – actually using it! I sprinkled some log messages throughout my code, like this:
*("Starting data processing...")
# ... some code that does stuff ...
*("Found a missing value in the dataset.")
# ... more code ...
*("Failed to connect to the database!")
I ran my script and boom! I saw the messages in my console, all nicely formatted. And when I checked the “mma_*” file, they were all there too! Success!
Improving It (A Little)
I realized later that sometimes I have function names so I made some changes.
I have add “%(filename)s:%(lineno)d”,so that I can got the log from where and * is easy for my debug.
Wrapping Up
So, that’s my basic logging setup. It’s not super fancy, but it’s working great for me. It’s helping me keep track of what’s going on in my code, and I can easily look back at the logs if something goes wrong. I might explore some more advanced features later, but for now, this is perfect. I think I can start working on my project.
