Using count() from Python's itertools module and the Tkinter GUI toolkit's after() function, you can create a simple counter that counts up the seconds until the Stop button is pressed.

This code takes a string a cyphers it by shifting it's position in the alphabet. I've gotten it so it can pretty much take paragraphs. It's quite neat to play with. For example the above when shifted to 5, would be: Ymnx htij yfpjx f xywnsl f hDumjwx ny gD …

User can enter an ascii string of up to 48 characters consisting of 1's or 0's, with randomly interspersed whitespace.

The wxPython GUI toolkit has a nice numeric LED widget (LEDNumberCtrl from the wx.gizmos module) that is used here for displaying the current time in very visible 7 segment LED color display. It also shows the application of the time module and wx.Timer(). The code is simple as far as …

A small demo about how to use GTK label as a simple console. To compile GTK program, `pkg-config gtk+-2.0 --cflags --libs` should finally be somewhere in the compiler command line in the bash-like shell.

Gives different combinations(Permutations) of string in input

Replaces every occasion of the pattern, or only the first occasion if there is a subexpression, between \( and \), anywhere in the regular expression, as repeated replace is not what one would expect in that case. The string size is restricted in POSIX regular expressions to the size of …

This filters out the letters and numbers in the parameters you give it.

Here are some functions I made for SDL abstraction:

a string which can be used ala std::string, preserves case, but comparisons are not case sensitive.

THE program highlights how to create a 2d array in freestore using pointers.. this is my first post so if i commit any fallacies regarding protocol or syntax please forgive me ....

This would let you store different things of same type into one data structure, here its a list. A good and popular example would be file and folder hierarchical structure in your computer. Perhaps this is what this code demonstrates. The code has two classes [INLINECODE]File [/INLINECODE]and [INLINECODE]Directory[/INLINECODE](derived from File). …

Problem Description ----------------------- I tried to download my favourite site containing essays on history (leeching) with depth 4.

This simple Python code uses the Tkinter GUI toolkit and the Python Image Library (PIL) to create a program that allows you to grab an image of the display screen (or portion of it) and save it to an image file. Unfortunately, the ImageGrab.grab() method only works on a Windows …

Just a little mathematical exercise in geography, namely the use of longitude and latitiude coordinates to calculate the distance between two given cities. You can obtain the coordinates for just about any earthly city from [URL="http://www.ASTRO.COM"]WWW.ASTRO.COM[/URL]. The coordinates are in a format like 35n13 (35 degrees, 13 minutes north). The …

Here is a little spinner thing for the command line, used when your current bash script is waiting on a background/system process. The weird character is ^H or a backspace.

------------------------------------------------------------ [COLOR=Blue][B]Intro:[/B][/COLOR] This is a small program that measures the performance of given java classes. In snippet there are 2 classes: 1. TestClass.java contains all java classes that are being measured for performance, I've picked up Narue's Sorting Algorithms as AUT (application under test) 2. AJPerf.java: contains the aspect that …

Theres no doubting that using Java Swing is time consuming on load times. So heres a demo splash screen to keep your users captivated. You will need two classes for this example i.e. Splash.java and SplashWindow.java (remember line: 8 change this to match your splash image) just change the class …

choose a random element from a sequence when a. you do not know how many elements are there before hand b. you want to make one single pass through the sequence c. you do not want to use auxiliary storage

There are times when you have to layout widgets on a window area fairly well spaced apart. To do this with pack() or grid() will be more than frustrating, for these occasions place() with its absolute coordinates comes to the rescue. Here is some Python/Tkinter GUI code showing you how …

A closer look at some string methods, just having a learning experience and fun with this C# class. This program uses a simple MessageBox to display the results.

I could not resist to put this little utility into a GUI dress. The code shows you that the C# StringBuilder is nicely suited to create the binary string. Also included is a check to assure that the input is an all digit numeric string.

A quick look at finding a substring in a string and giving the position of the substring, if found. The string method IndexOf() has a number of options to explore.

C# has two types of strings, one is immutable and the other, the class StringBuilder, is mutable (dynamic). I just wanted to hang a short code snippet out there to show you some of the typical operations.

I followed Lardmeister's smart hints about creating templates with VC# 2003 and using SnippetCompiler.exe to write and test the rest of the program. It also allows you to build the executable (only 7k in size). The algorithm is from one of my Python snippets I wrote a long time ago. …

Here I made a GUI template with a Form, Button and Listbox using MS VCS 2003. MS VCS 2003 still produces a single file usable as a templet, whereas MS VCS 2005 smears files all over the map. Must be some marketing persons idea of market dominance. I took the …
