Wuforo Dua Pa A


Wuforo Dua Pa A means “when you climb a good tree”. It is the symbol of support, cooperation and encouragement.

We will use the 5 pixel grid to trace out this image. The image of this is shown below:


The plan to draw this shape is given below:

  1. Lift up the pen
  2. Set the pen size to 40
  3. Move the pen to the location (40, 0)
  4. Place the pen down
  5. Move forward by 70 pixels
  6. Lift up the pen
  7. Move the pen to the location (-40, 0)
  8. Set the heading of the pen to 180 degrees
  9. Place the pen down
  10. Move forward by 70 pixels
  11. Lift up the pen
  12. Move the pen to the position (-170, 50)
  13. Set the heading of the pen to 90 degrees
  14. Place the pen down
  15. Move forward by 120 pixels
  16. Set the heading of the pen to 0 degrees
  17. Move forward by 120 pixels
  18. Lift up the pen
  19. Move the pen to the position (-170, 50)
  20. Set the heading of the pen to 270 degrees
  21. Place the pen down
  22. Move forward by 120 pixels
  23. Set the heading of the pen to 0 degrees
  24. Move forward by 120 pixels
  25. Lift up the pen
  26. Move the pen to the position (170, 50)
  27. Set the heading of the pen to 90 degrees
  28. Place the pen down
  29. Move forward by 120 pixels
  30. Set the heading of the pen to 180 degrees
  31. Move forward by 120 pixels
  32. Lift up the pen
  33. Move the pen to the position (170, -50)
  34. Set the heading of the pen to 270 degrees
  35. Place the pen down
  36. Move forward by 120 pixels
  37. Set the heading of the pen to 0 degrees
  38. Move forward by 120 pixels

Using Turtle Graphics

We will use the template.py file and rename it to wuforo.py.

The code of the first five steps is given below:

turtle.penup()
turtle.pensize(40)
turtle.setposition(40, 0)
turtle.pendown()
turtle.forward()

The generated image is shown below:


The code for steps 6 to 10 is simply to repeat the initial steps. This is given below:

turtle.penup()
turtle.setposition(-40, 0)
turtle.setheading(180)
turtle.pendown()
turtle.forward(70)

The generated image is shown below:


Drawing the rest of the symbol will involve lifting up the pen and moving around the shape. We will start with the upper left quadrant, move to the lower left quadrant and follow the same pattern in the right quadrant.

The code for steps 11 to 16 is shown below:

turtle.penup()
turtle.setposition(-170, 50)
turtle.setheading(90)
turtle.pendown()
turtle.forward(120)
turtle.setheading(0)
turtle.forward(120)

The generated image is shown below:


The code for steps 18 to 24 is shown below:

turtle.penup()
turtle.setposition(-170, -50)
turtle.setheading(270)
turtle.pendown()
turtle.forward(120)
turtle.setheading(0)
turtle.forward(120)

The generated image is shown below:


Steps 25 to 31 will draw the parts of the symbol at the upper right hand corner. The code to do this is shown below:

turtle.penup()
turtle.setposition(170, 50)
turtle.setheading(90)
turtle.pendown()
turtle.forward(120)
turtle.setheading(180)
turtle.forward(120)

The generated image is shown below:


To complete this symbol, the code for the lower left part is shown below:

turtle.penup()
turtle.setposition(170, -50)
turtle.setheading(270)
turtle.pendown()
turtle.forward(120)
turtle.setheading(180)
turtle.forward(120)

The generated image is shown below:


Conclusion

This shape wasn't much of a stretch to draw. It was based on repeating the patterns for drawing.
