Answer

Pseudo Code for Tree Drawing Function

This pseudo code represents the logic implemented in the provided Python function tree(), which is designed to draw a tree using turtle graphics.

Main Function: tree()

Initialize the drawing environment
- Move the pen up to avoid drawing
- Position the turtle at coordinates (250, -320)
Set Pen Properties
- Set the pen size to 10
- Set the pen color to black
- Set the fill color to salmon4
Draw the Tree Trunk
- Move the pen down to start drawing
- Begin filling the shape
- Set the heading to 87.5 degrees
- Move forward by 295 units (draw trunk)
- Move backward by 295 units (return to original starting point)
- Set the heading to 0 degrees
- Move forward by 100 units (position for next part)
- Set the heading to 92.5 degrees
- Move forward by 295 units (draw second side of trunk)
- Turn left by 90 degrees
- Move forward by 78 units (complete trunk drawing)
- End filling the shape
Draw the Tree Canopy
- Move pen up to avoid drawing
- Position at (285, 160)
- Move pen down to start drawing
- Set fill color to green4
- Begin filling the circle
- Draw a full circle with radius 100
- End filling the canopy
Draw Red and Orange Decorations
- Move pen up to avoid drawing
- Position at (350, 20)
- Set heading to 45 degrees
- Set fill color to red
- Begin filling the shape
- Draw a quarter circle with radius 45
- Draw a quarter circle with radius 12.6
- End filling red shape
- Set fill color to orange
- Begin filling the shape
- Draw a quarter circle with radius 45
- Draw a quarter circle with radius 12.6
- End filling orange shape
Repeat Decorations in Different Positions
- Move pen up to avoid drawing
- Position at (280, 0)
- Set heading to 45 degrees
- Set fill color to orange
- Begin filling the red shape
- Draw a quarter circle with radius 45
- Draw a quarter circle with radius 12.6
- End filling red shape
- Set fill color to orange
- Begin filling the shape
- Draw a quarter circle with radius 45
- Draw a quarter circle with radius 12.6
- End filling orange shape
Continue with Additional Decorations
- Move pen up to avoid drawing
- Position at (300, 70)
- Set heading to 45 degrees
- Set fill color to orange
- Begin filling the red shape
- Draw a quarter circle with radius 45
- Draw a quarter circle with radius 12.6
- End filling red shape
- Set fill color to orange
- Begin filling the shape
- Draw a quarter circle with radius 45
- Draw a quarter circle with radius 12.6
- End filling orange shape

Summary

The function draws a tree structure with a trunk, a canopy, and decorative elements using turtle graphics commands.
It effectively demonstrates manipulation of turtle movement and shape filling in a structured way, clarifying each step with dedicated comments for better understanding.

This pseudo code serves as a clear blueprint for developers to implement or modify the tree drawing function using turtle graphics in Python, enhancing communication and documentation.
