I started using Python a few weeks ago, something finally clicked and I started writing tools for my personal use. I started writing something with a GUI using GTK and the code lines started multiplying rapidly, so I thought to myself "Am I commenting my source to death? How many …

As in C++ was some question about speed of simple hard disk based lookup, here is a version of unscramble program completely HD based lookup, which gives all possible candidate words for multiword anagram. Program is not sensitive for case of words but does not ignore special characters like ' …

This is a script that was supposed to be very basic, just running a command with my scripts arguments attached. I didn't realize that if user 'cj' opens firefox, when user 'root' does '**firefox -new-tab**' it doesn't work. Firefox will just open a new window, and thats exactly what I …

Hi all! This is a simple piece of code that I wrote about a year ago, in response to a question on Daniweb. I decided to infuse it with some C++11 magic, which led to a pretty sweet code snippet, full of neat little techniques you might want to use, …

With both subs you must enter the values as you would write them into a sql string i.e. 'mustsurroundstrings' I'm rather new at VB.Net and SQL but these work for me and are seem pretty efficient. If anyone has a way to improve on them or finds a flaw in …

While not terribly difficult, first timers may not know the functions to look up and use. Here is some basic code for reading a file one line at a time. The contents of the file are printed to the stdout.

To Shift the Three Numbers a,b,c in Circular order

Here's some simulation of the basic push_back and pop_back functions from stl vectors, "inspired" by this thread: http://www.daniweb.com/software-development/cpp/threads/427912/question-about-a-simple-vector-class-template

This is a simple game of pong with made using pygame. You will need to make a picture of the pong for it to run properly. Simply make a cirlce in paint, 25x25. Joe

I wrote this program because I often am asked by people that know that I like to make games to make just a quick simple game for some reason or another. I always make a simple text based adventure game (like Zork, but simpler) and they are usually happy with …

Because of [C++ code snippets not dealing with multiple +-](http://www.daniweb.com/posts/jump/1829367) in sequence (or even negative number) in expressions, I post this, as it is so much easier for me than C/C++. EDIT: Fixed signs together with '(' issues and '+' at beginning removing without lstrip, removed separate now unused '(' …

This is bit funny code as you can first read from this excellent response: http://www.daniweb.com/software-development/python/threads/427341/custom-types-in-a-simple-way#post1828718 why should you not use it, even it maybe feels useful. Anyway I got curious to see how type signature could be implemented, even using it would generally just be stupid way of slowing down …

This is a program which I made back in the beginnings when I was trying to figure out how to work with strings, and how to work with files. This is suppose to format a C++ code, for example if the syntax of an if statement is if (condition) { …

This is a goofy sentence generator I have made in python; it took about 5 minutes to get the code to work - but its working now so if your curious try it out!

The `ReplaceStrings` function replaces all strings in `APatterns` found in `ASubject` with the value in `AReplacement`. As an example, I added the `RemoveStrings` function which replaces everthing with an empty string, thus deleting all strings found. Usage examples are in the XMLDoc comments. A good test will be to rewrite …

To Find the Prime Factors of Given Number

To Check Whether the Given Point P is inside a Triangle or Not..

Here you see how one could use recursion together with generators for (inefficient) permutations generator. It is kind of interesting to know how one can do it recursively (of course there exist many ways). Anyway this snippet demonstrates how you can use recursive generator call to feed a for statement. …

I googled little around for correct way to not reinventing of the wheel for expression evaluation (even I had done some simple evaluation check for my [Tkinter calculator snippet](http://www.daniweb.com/software-development/python/code/282548/simple-calculator) earlier). After getting totally upset with [this example](http://www.bestcode.com/html/evaluate_math_expressions_pyth.html), I made this with some struggles with `__builtins__` globals parameter of eval. First …

Inspired by some C and C++ threads regarding finding a specific pattern in a file.

When working whith large data files, it may be desirable to output a sequence of bytes by large chunks. This snippet defines a file adapter class to handle this transparently. Writing bytes to an ChunkedOutputFile will automatically write the underlying file object by fixed length chunks.

Hello everyone, this is something I wrote a couple months back. It is used as a universal class/object loader from an XML file. For the handling of XML I use the JDOM library. The story basically goes like this: I have a load of classes in a game I'm working …

Sometimes we want to tackle some problem specifying properties of sequence of numbers consisting the integer. Then it is usefull to have function to join many integers to make a long integer. Most efficient way for tight loops is to stay in integers domain and not go through the string …

Finding efficiently primes, whose begining numbers are also primes. See the thread http://www.daniweb.com/software-development/cpp/threads/425821/prime-number-c in C++ forum for discussion on topic.

Programming just for fun.

Simple conversion between string and int.

Hi! This is my submission for code snippet contest. I also posted this code to help other members on how they can use compact & repair their MS Access Database within Visual Basic 6.0. You also need to add Microsoft Jet and Replication 2.6 in your project reference. To use, …

This code snippet allows you to list the files in a folder sorted by "last modified date". The tuple returned by the os.stat() function contains amongst other things the last modified date, which is then converted by the time.localtime() function to a tuple that is ideal for sorting. You can …

We can run Python2 script in most simple cases if we just use the 2to3.py script found in recent Python versions: F:\Python27\Tools\Scripts>copy \test\output_window_tk.py \test\output_window_tk2.py 1 tiedosto(a) on kopioitu. F:\Python27\Tools\Scripts>2to3.py -w \test\output_window_tk.py RefactoringTool: Skipping implicit fixer: buffer RefactoringTool: Skipping implicit fixer: idioms RefactoringTool: Skipping implicit fixer: set_literal RefactoringTool: Skipping implicit fixer: …

Since I keep seeing people asking how to read the Integers from a File, I figured this simple snippet might be useful. What it does is it creates a new Scanner Object based on the File Object "test.txt" then it reads all of the Integers from that file, skipping over …

Just a couple basic static mathematical helper methods that I've found useful for game development. Feel free to add some in replies for future visitors. I will do another post later this week with advanced helper methods from trig and calc. I will also do a geometry helper class as …

This python 2 code snippet uses unicode chess symbols and box drawings symbols to display a chessboard in a terminal. With a terminal profile having a monospace font of size 20 or more, it looks quite usable to play chess.

i don't know how it happen but the exe formed after compilation was 1.23 MB which has never happen before.

Simple code to see if array of primitives has duplicates. The aim is to only check if there are any duplicates, but not to check what element is repeated, or its position etc. PS: Do you know some handy snippet? Don't way, post it!

This code demonstrates how to add controls to a form at run time. The number of rows and columns, the spacing between the controls and the size of the controls are all determined by Consts, but this could easily be changed so that the parameters are user entered. My example …

Hello Guys, I was performing text file reading and writting operations and the job looked very simple as usual, yet it has not been solved successfully. We have got a simple text file **final.txt** which contains data like this:- **05/18/2012 02:12:66 8HRY hjhruehr737243 YES NO u34gewryge 698** i.e each value …

Figured I've been working on material for a while and would throw these up for everyone that needs them in the future to use. It's very simple implementation; if I get enough people asking me to, I will write the methods for each of the instructions so you don't have …

I had a small problem with collision detection starting out with XNA 4.0 so I figured I'd release a simple snippet that helps with two different types of collision detection; Per-Pixel and Rectangular. To use simply copy and paste the snippet into your current source, or you could put it …

have fun with this game o' keno! post here with your highest winnings

I borrowed this from C#, where you can easily send output, that normally goes to the ugly black console window, to a nice looking Windows MessageBox with an OK button to close after you read your results. You can accumulate your output in a string to send to one message …

 I was tired of always looking for a way to underline labels like in Windows property dialogs. I created this little control that allows you to set a two-tone line above, below behind or in front of a label (even through it!) to solve that problem. The image …

Gribouillis has allready posted code similar to this in his snippets, but here version for input suitable for for expressions, generators and list comprehensions. Need to add robustness by some try...except blocks for real world use.

This code snippet provides methods to convert between various ieee754 floating point numbers format. For example double precision to single precision. The format is given by a pair (w, p) giving the size in bits of the exponent part and the significand part in the ieee754 representation of a number …

I get tired of having to google this simple line of code all the time. My problem with memorizing it is that I switch back and forth between C# and C++ all the time, and the way you overload operators in each is different. So once I learn one again, …

This came up, maybe it is usefull to somebody. Later I plan to do a managing context interface to `with`statement for this.
