Boston Python Workshop/1/Saturday/ColorWall
Program graphical effects for a ColorWall using the Tkinter GUI toolkit. See the ColorWall in action here.
See the Friday setup instructions.
- Have fun experiment with and creating graphical effects.
- Practice using functions and classes.
- Get experience with graphics programming using the Tkinter GUI toolkit.
Find and change the colors used in the
Checkerboardseffect, and re-run the effect:
python run.py Checkerboards
Then change the line
if (x + y + i) % 2 == 0:
if (x + y + i) % 3 == 0:
re-run the effect, and see what changed.
Find and change the color of the columns in the
Matrixeffect, and re-run the effect:
python run.py Matrix
Each column that we see on the wall corresponds to a
Columnobject. Add some randomness to the color used by each column (the variable whose value you changed above) using the
random.randomfunction, re-run the effect, and see what happens.
Twinkle. Find explanations of the
random.uniformfunctions in the online documentation at http://docs.python.org/library/random.html. Experiment with these functions at a Python prompt:
import random random.randint(0, 1) random.randint(0, 5) random.uniform(-1, 1)
Then experiment with the numbers that make up the hue and re-run the effect:
python run.py Twinkle
- Write your own effects!
