### Nnampo Pa Baanu

Nnampo Pa Baanu means "two good friends". It is the symbol of friendship.

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 pensize to 40 pixels
3. Move the pen to the bottom of the  location of the center vertical
4. Draw the center vertical
5. Set the pensize to 30 pixels
6. Draw the remaining center verticals
7. Complete the outline of the shape
8. Draw the semicircles
Using Turtle Graphics

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

The code for steps 1 and 2 is given below:

turtle.penup()
turtle.pensize(40)

The coordinates for the bottom of the center vertical are (0, -80). The length of the line is 160 pixels.

The code to draw this line is shown below:

turtle.setposition(0, -60)
turtle.pendown()
turtle.setheading(90)
turtle.forward(120)

The generated image is shown below:

To draw the remaining center verticals, we must first know their coordinates they are: (-165, 60), (-85, 60), (85, 60) and (165, 60).

The code to draw them is given below:

turtle.pensize(30)

turtle.penup()
turtle.setposition(-165, -60)
turtle.pendown()
turtle.setheading(90)
turtle.forward(120)

turtle.penup()
turtle.setposition(-85, -60)
turtle.pendown()
turtle.setheading(90)
turtle.forward(120)

turtle.penup()
turtle.setposition(85, -60)
turtle.pendown()
turtle.setheading(90)
turtle.forward(120)

turtle.penup()
turtle.setposition(165, -60)
turtle.pendown()
turtle.setheading(90)
turtle.forward(120)

The generated image is shown below:

To complete the outline of the shape, we need to draw the top horizontal line and the bottom horizontal line.

The coordinate for the upper line is (-165, 75) and its length is 330 pixels. The code to draw it is shown below:

turtle.penup()
turtle.setposition(-165, 75)
turtle.pendown()
turtle.setheading(0)
turtle.forward(330)

The coordinate for the lower line is (-165, -75). The code to draw it is shown below:

turtle.penup()
turtle.setposition(-165, -75)
turtle.pendown()
turtle.setheading(0)
turtle.forward(330)

The generated image is shown below:

Drawing the semicircles is easy. We need to move the turtle to the position of the rightmost sides and draw the circle.

The code to do this is shown below:

turtle.penup()
turtle.setposition(165, 75)
turtle.pendown()
turtle.setheading(90)
turtle.circle(80, 180)

turtle.penup()
turtle.setposition(-5, 75)
turtle.pendown()
turtle.setheading(90)
turtle.circle(80, 180)

The generated image is shown below:

To draw the lower semicircle we just invert the positions. The code to do this is shown below:

turtle.penup()
turtle.setposition(-165, -75)
turtle.pendown()
turtle.setheading(270)
turtle.circle(80, 180)

turtle.penup()
turtle.setposition(5, -75)
turtle.pendown()
turtle.setheading(270)
turtle.circle(80, 180)

The generated image is shown below:

Conclusion

At the end of this section we have succeeded in drawing the Nnampo Pa Baanu symbol.

This post is part of the series: Drawing Adinkra Symbols using Python. The goal is to draw 40 Adinkra symbols using the Python programming language.
