### Kuntinkantan

Kuntinkantan means “puffed up extravagance”. It is the symbol of arrogance.

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

This shape is easy to draw. It consists only of circles. It is a made up of a central circle that encloses the other 4 circles.

The plan to draw this shape is shown below:
1. Lift the turtle
2. Set the pen size to 20 pixels
3. Move the turtle to the position (0, -90)
4. Place the pen down
5. Draw a circle of radius 90 pixels
6. Lift up the pen
7. Move the turtle to the position (-90, 10)
8. Place the pen down
9. Draw a circle of radius 80 pixels
10. Lift up the pen
11. Move the turtle to the position (90, 10)
12. Place the pen down
13. Draw a circle of radius 80 pixels
14. Lift up the pen
15. Move the turtle to the position (-90, -170)
16. Place the pen down
17. Draw a circle of radius 80 pixels
18. Lift up the pen
19. Move the turtle to the position (90, -170)
20. Place the pen down

### Kete-Pa

Kete-Pa means "good bed". It is the symbol of a good marriage. It is derived from the expression that a woman who has a good marriage is said to sleep on a good bed.

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

This shape is easy to draw. It consists only of straight lines. This lines are horizontal and vertical.

The easiest way to draw this symbol is to use a loop. We will draw the horizontal symbols first and the vertical symbols next.

Thankfully in our template we already have functions that can do this. They are the drawHorizontalLine and drawVerticalLine functions.

The plan to draw this symbol is shown below:
1. Set the pen size to 10 pixels
2. Use the drawHorizontalLine function with 11 divisions
3. Use the drawVerticalLine function with 11 divisions

Using Turtle Graphics

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

The code for step 1 is given below:

turtle.pensize(10)

The code for step 2 is given below:

drawHorizontalLine(330, 11)

The code for step 3 is given below:

drawVerticalLine(330, 11)

The generated image is shown below:

Conclusion

At the end of this section, we have successfully used Python turtle to draw the Kete-Pa symbol.

This is one of the easiest symbol to draw because it is made up of lines.

Thankfully, we have no need to do any coding because we simply needed to use the functions in our template file.

### Fofoo

Fofoo means "yellow flowered plant". It is the symbol of jealousy and envy. When the fofo's petals drop, they turn into black spiky-like seeds. The Akan liken the nature of this plant to a jealous person.

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

This symbol consists of lines and circles. The inner circle is of a radius of 3 squares. The outer rim is of a width of 3 squares. The line from the rim to the outer circle is of 4 squares in width. Its length starts from around the point where the distance from the centre is 5 squares. It stretches up to the point which is 13 squares from the centre of the circle. The line is closed up by a filled circle. Its radius is 3 squares.

The plan to draw this symbol is as follows:

1. Lift the turtle
2. Move it to the position that is 5 squares from the centre of the symbol
3. Place the turtle down
4. Set its pensize to 4 squares
5. Draw a circle of a radius of 5 squares
6. Lift up the pen
7. Move it back to the centre of the symbol which is at the origin
8. Set the pensize to 3 squares
9. Set the heading of the turtle to 90 degrees
10. Move to the position that is 5 squares from the centre of the circle in the direction of the heading of the turtle
11. Place the turtle down
12. Draw a line by moving forward by 8 squares
13. Set the orientation of the turtle based on the formula (heading - 90)
14. Set the pensize to 1
15. Draw a filled circle from the point the line stops
16. Go back to step 6 but each time you get to step 9, increase the heading by 40 until you get to 410

Using Turtle Graphics

We will use the template.py file and rename it to fofoo.py. The size of each square on our grid is 10 pixels. We shall use this as our multiplication factor.

From our first step, we need to lift up the pen. The code to do this is shown below:

turtle.penup()

To move the turtle to the point that is 5 squares from the center of the figure, we want to move it to the location that is (0, -5). Due to the multiplication factor of 10, this will now become (0, -50). The code to do this is given below:

turtle.setposition(0, -50)

To place the turtle down. The code to place the turtle down is shown below:

turtle.pendown()

To set the pensize to 4 squares, we will multiply this by 10 to get 40. The code to do this is shown below:

turtle.pensize(40)

We need to draw a circle of radius 5 squares. We use our multiplication factor and the value becomes 50. The code to do this is shown below:

turtle.circle(50)

The image that is generated is shown below:

Steps 6 to 12 are summarized by the steps shown below:

turtle.penup()
turtle.home()
turtle.pensize(30)
turtle.forward(50)
turtle.pendown()
turtle.forward(80)

The generated image is shown below:

The code for steps 13, 14 and 15 are given below:

turtle.pensize(1)
turtle.begin_fill()
turtle.circle(30)
turtle.end_fill()

The generated image is shown below:

Step 16 indicates that this is a loop. So we go back to step 6.

Now it would be easier to just use a simple while loop. So delete all the code for step 6 to step 15 and just enter this:

turtle.penup()
turtle.home()
turtle.pensize(30)
turtle.forward(50)
turtle.pendown()
turtle.forward(80)
turtle.pensize(1)
turtle.begin_fill()
turtle.circle(30)
turtle.end_fill()
