Diamond
Write a Python program that uses turtle graphics to draw a diamond.
Example
Centered Square
Write a Python program that uses turtle graphics to draw a square that is centered in the window.
Example
Note, it is difficult to see if the square is correctly centered when the square is small and the window is large. Draw the square large so that it takes up the majority of the window to make it easier to tell if it is perfectly centered.
Star
One of the first shapes you learned to draw in grade school was probably a star. It is a pretty easy shape to draw, looks pretty cool, and can be done entirely with straight lines. The only tricky part is determining how to go from one point of the star to the next. Today, you will figure that part out.
Details
In Emacs, create a Python program in a file called star.py. Your program should use the turtle module to draw a five-pointed star.
Example
- Drawing the star is much easier if you use the
functions
turtle.forwardand eitherturtle.leftorturtle.right. - Note that the turtle will need to turn once for each point of the star and that it will turn a total of 720°. So, you can calculate the number of degrees in each turn.
- Finally, drawing the star is simply alternating between moving forward and turning.
One of the great advantages to using a computer for drawing is that it is possible to draw precisely. It makes creating something perfectly symmetrical very easy.
Details
In Emacs, create a Python program in a file called house.py. Your program should use the turtle module to draw a simple house. The house should be a square with a triangle for a roof, and a rectangle for a door. The house should be symmetrical about a vertical line.
Example
The trickiest part of the house is getting the roof to fit perfectly. To get it to fit perfectly, you need to calculate the angle of the roof and the length of the roof edges. If you use a 45-45-90 triangle, then the roof angle 45 is degrees and the roof length is the house width divided by the square root of 2.
Challenge
Spruce up the house. Add things like a chimney, the sun, a tree, a mailbox, a fence, whatever you want, as long as it impresses me.
