Python – Comparing against multiple items

I see this scenario and solution more often than I probably should: you have a value that needs to be compared against multiple possible values, and if there is a match perform a certain action. Usually the solution to this common event is to create a series of if...elif...else conditions, one for each possible value, running the commands after each passing condition, and using the else clause as the non matching case. An example of such a condition would be like so:

Triangle Land refresh & the future

I think I link this song every time I post about my future plans. Whatever, I like this song. 😛

P.S. If you are reading this on WordPress.com, you already know the big changes, but if you are reading any other way, you will need to come to my site. 😉

Blocks v1.0.0

Blocks has always been a landmark application for me. What began life known as “The Blocker” and a simple command window quickly transformed into my very first full-GUI application, and continued to be a landmark by performing syntax checks on the files it created, something I had not tried before. Blocks has also been the informational resource for the (still incomplete) Building With Blocks tutorial, which examines the file format in context of manually modding the Island Xtreme Stunts Trouble in Store mini game levels.

It has been over a year since the last release of Blocks, namely v0.9.1. Just like my other projects, Blocks was put on hold because of college work. Although I have had some time to work on JavaScript-based projects since then, for a while I have been longing to get back to some Python programming. In order to transition back, I decided to work on a smaller project, a category in which Blocks in a member. Today, I am proud to announce yet another milestone release of Blocks v1.0.0!

Python – Normalize User Input

After remaining in drafting for over a year (initial draft was on 7 August, 2013), I have finished this new Python tutorial. There is a lot to be written about case normalization, both for the upsides and downsides, but it is generally agreed upon that user input should be normalized, or converted into such a form that any checks run on the input can be case-insensitive. This tutorial shows how you can do that and provides a through example of case normalization in action. No, just because I use the term “in action” does not mean it is your favorite or the newest theatrical action movie. 😛

Enjoy. 🙂

LR2 Track Selector and LR Track Selector v2.0

A long time ago in a place not far from here, a certain triangle wrote a program to randomly select tracks from the game LEGO® Racers for the player to race. Soon thereafter, a friend asked for an equivalent version for LEGO® Racers 2. The request was acknowledged, and work so began. However, due to confusing logic and a lack of programming skills needed to carry out such a task, development was halted, and the request was never fulfilled.

One year later, the unfinished program was referenced, and after reviewing the state of the code, it was decided that the know-how required to complete it was now available. A mere two hours later, the program had been finished, and the promise made had been kept.

Count the number of lines in a file – Python

This is a super simple tutorial. So simple, in fact, it is the shortest one I have ever written.

If you ever need to count the number of lines a file has in it and not even process the file, only count the lines, simply open the file and use a for loop to iterate over the number of lines and update an incrementer already in place. No need to even read the contents.

(View on GitHub Gist)

I told you this was a super simple and short tutorial. 🙂
