    The little snake fun as the sketch group


Hello world made easy

print "Hello world!"

Make it even cooler with pygame

# Import modules
import pygame
from pygame.locals import *


salutation = "Hello World !"

# Initialize
pygame.init ()
size = (256, 128)
window = pygame.display.set_mode ( size )

hellofont = pygame.font.SysFont ( 'courier', 16, True, True )
hellosurf = hellofont.render ( salutation, 1, Color("white") )
hellorect = window.blit ( hellosurf, (16, 16) )
pygame.display.update ( hellorect )

# Loop
loop = True
while loop is True:
   
    for evnt in pygame.event.get ():
       
        if evnt.type is QUIT:
            loop = False
           
        if evnt.type is KEYDOWN:
           
            if evnt.key == K_ESCAPE:
                loop = False

            if evnt.key == K_RETURN:
                window.fill ( Color("black"), hellorect )
                pygame.display.update ( hellorect )

    pygame.time.wait(250) # waiting 250 milliseconds makes it not too hasty


# Quit
pygame.quit ()



    Pyctor




Here an extract of an example session which produced the image above.

Example, version 1.5


name: math_art_1.bmp
size: 256, 256

valid parameters in functions are

    b      blue
    rfunc  red function
    g      green
    h      256
    gfunc  green function
    r      red
    bfunc  blue function
    w      256
    y      vertical position
    x      horizontal position
    size   (256, 256)

red function: x**2+y**2
green function: (x-w)**2+(y-h)**2
blue function: (x-w/2)**2-(y-h/2)**2

With the second version



Example, version 2

       ** Pyctor 2.0 **

    WebKLF


WebKLF 2
It is a python application powered by pygame to retrieve a specific information from an Internet source.
In this case it is specifically got from the html source of www.klf.fi
Myself, I like much the interface in the application.

The projects has been configured on Windows XP with Python 2.6.
It would be nice if some of you tried this out on another platform. Some of the features might not work on every one.


    Platforms


  • Windows XP or higher, Vista
  • Linux


    Features


  • Withdraw and display of information from www.klf.fi
  • Colored text on console window (Win)
  • Optional username search from OS environment variables (Win)

  • pygame <=1.8.1 release
  • os
  • sys
  • urllib2

It is a python pygame powered application to retrieve a specific information from an Internet source.
It is flexible so that users can define their keyword and url.
It is based on WebKLF, which is an earlier project of mine.
