EduWorld 0.0.40

Educational package to learn computational thinking and other basic programming concepts

EduWorld

EduWorld is an educational python package designed for students to learn computational thinking, algorithms, and other basic programming concepts. Through this process they learn how to divide a problem into smaller steps and refine them; to abstract; to recognize patterns; and to design and implement algorithms;

Robot

Conceptually it is based on Kumir Robot, with bits of Karel the Robot. (but shares no code)

• https://github.com/a-a-maly/kumir2
• https://github.com/TylerYep/stanfordkarel
• https://github.com/xsebek/karel

The Robot can walk in four cardinal directions, sense walls, temperature, radiation, and place/pickup beepers.

See the eduworld.robot module for the list of all available procedural commands.

Oop version of the Robot is not yet completed and somewhat clumsy to use.

Interactive mode

from eduworld.robot import interactive_mode

interactive_mode()

To launch Robot in interactive mode (immediate command execution), run python test_robot.py. In this mode Robot will not execute error shut-off even if you run it into the wall.

Command keys

• W - move up
• S - move down
• A - move left
• D - move right
• E - paint tile
• R - pickup beeper
• F - put beeper
• Q - quit
• P - Save current world into out.aww file
• KP_8 - Toggle tile top wall
• KP_6 - Toggle tile right wall
• KP_2 - Toggle tile bottom wall
• KP_4 - Toggle tile left wall

Plotter

The Plotter is used to paint lines on endless sheet of paper. It is conceptually based on Kumir Plotter, but with few extras.

See the eduworld.plotter module for list of available commands.

Interactive mode

from eduworld.plotter import setup, shutdown


setup(interactive=True)
shutdown(keep_window=True)

To launch Plotter in interactive mode run python test_plotter.py. In this mode you can control plotter's head using following keys

• Keypad 8 - move up 1 unit
• Keypad 2 - move down 1 unit
• Keypad 4 - move left 1 unit
• Keypad 6 - move right 1 unit
• Keypad 9 - move up-right 1 unit
• Keypad 3 - move down-right 1 unit
• Keypad 1 - move down-left 1 unit
• Keypad 7 - move up-left 1 unit
• Keypad 0 - Move pen to origin (0, 0)
• Keypad - - zoom out
• Keypad + - zoom in
• W - randomly pick pen width
• E - randomly pick pen color
• R - raise pen
• F - lower pen
• Z - undo last line
• C - erase drawing

When you shutdown() Plotter with keep_window=True, you can use Keypad to move around the paper sheet.
