2. Getting Started — Python GTK+ 3 Tutorial 3.4 documentation. 2.1.
Simple Example¶ To start with our tutorial we create the simplest program possible. This program will create an empty 200 x 200 pixel window. We will now explain each line of the example. Ragnamus (Matthew Truscott) PyGUI. Latest Version - 2.5.4 Now works with Python 3 on MacOSX and Windows!
(Python 3 support for Gtk will have to wait until Gtk 3 and related libraries are stable and up to speed with GObject Introspection.) The ScrollableView class has been completely reimplemented on Windows and should now work properly with all builds of PyWin32.

For the most part, Python aims to be a clean and consistent language that avoids surprises.
However, there are a few cases that can be confusing to newcomers. Some of these cases are intentional but can be potentially surprising. Some could arguably be considered language warts. In general though, what follows is a collection of potentially tricky behavior that might seem strange at first glance, but is generally sensible once you’re aware of the underlying cause for the surprise. Mutable Default Arguments Seemingly the most common surprise new Python programmers encounter is Python’s treatment of mutable default arguments in function definitions.
What You Wrote def append_to(element, to=[]): to.append(element) return to What You Might Have Expected to Happen my_list = append_to(12)print my_list my_other_list = append_to(42)print my_other_list A new list is created each time the function is called if a second argument isn’t provided, so that the output is:

This week, I decided to take a little breather from my current project, GameLad, and hack on something that I've been interested in for a long time now: raycasting.
I'll start with some history. Raycasting is not, by any means, a new technology. It's been around for a while, and was, perhaps most notably, used for the 1992 game Wolfenstein 3D. In the days of early gaming, computers were too slow to render 3D graphics in realtime, and developers needed an alternative rendering technique. Thus, raycasting was born. It isn't exactly a simple technique, as it requires some knowledge of trigonometry, but compared to writing a full 3D renderer, implementing a raycaster is a piece of cake.
The Map The game world is represented in an array of integers. The Player There are only a few variables needed for the player: the position, the direction, and the camera plane. Vector2D position(14.5, 20); Vector2D direction(0, -1); Vector2D cameraPlane(1, 0); The Raycasting bool hit = false; int side; while (! How to Write a Roguelike in 15 Steps. This is a rough route map for the creators of roguelikes.
I'm well aware that there are many possible routes and that no two journeys are the same -- this is a description of one of possibilities and maybe will help you to plan your own. Please add your comments -- maybe we could make this article really helpful. What are your own routes? There is a school of thought in programming that data structures are more important than code: once you have the data structures right, the code will be self-evident.
It may be useful to think before embarking about how you want to structure spatial information, a list of map tiles and their properties, character information, monster/NPC information, and information regarding objects and marks/sound/scent/footprints or tracks on the map (if at all). Step 1 - Decide to write a game Most of you will have this step behind you already, but there are some hints about the direction of the first step. External Table: How to Build a Neural Network Scoring Engine in PL/SQL. Topic: In this post, you will find an example of how to build and deploy a basic artificial neural network scoring engine using PL/SQL for recognizing handwritten digits.
This post is intended for learning purposes, in particular for Oracle practitioners who want a hands-on introduction to neural networks. Introduction Machine learning and neural networks in particular, are currently hot topics in data processing. Many tools and platform are now easily available to work and experiment with neural networks and deep learning (see also the links at the end of this post). Recognizing hand-written digits, in particular using the MNIST database by Yann LeCun et al., is currently the "hello world" example for neural networks.
One of the ideas that this post wants to illustrate is that scoring neural networks is much easier than training them: the operations required for serving a trained network can be implemented relatively easily on many computing languages/environments.
