PYTHON: A Turtle Graphics Project

A Halloween Greeting

A Carved Pumpkin (October 2022)

This is a python program that draws a Halloween Pumpkin Greeting:

We start off by importing the turtle module into our program:

import turtle

#Set variables to zero
count=0

We now have to set up the screen.

I have decided to set the background for this program to a deep purple - the hex value of this I ascertained from a graphics program.

I have set the cursor to be a witch on a bloom (with her cat), and included a greeting graphic and a logo for my site.

These images have to be imported from my Trinket library - it takes png and gif images.

You can see how I incorporate the graphics below:

screen=turtle.Screen()

screen.setup(500,500)

screen.bgcolor("#240024")

screen.addshape("witchOnBroom60right2.png")

screen.addshape("HappyHalloween.png")

screen.addshape("logo.png")

I now need to set up the 'turtles'. The greeting image and the logo are 'turtles' - but the main one is the one that will have the witch as the graphic.

logo=turtle.Turtle("logo.png")#The 'logo' Turtle

logo.shape("logo.png")

logo.up()#It is necassary to lift up the turtle to move it without making a line on the screen

logo.rt(270)

logo.goto(150,-240)

logo.down()#Now it is where I want it - I can put it down!

text=turtle.Turtle("HappyHalloween.png")#The text Turtle

text.shape("HappyHalloween.png")

text.up()#It is necassary to lift up the turtle to move it without making a line on the screen

text.goto(0,150)

text.down()#Now it is where I want it - I can put it down!

text.rt(630)#Wheeling it around!

text.up()

turtle = turtle.Turtle("witchOnBroom60right2.png")#Set up turtle to draw pumpkin

turtle.shape("witchOnBroom60right2.png")#A witch will 'draw' the figure

turtle.color("#B74900")#The colour of the line drawn will be a very dark orange (hex colour selected from a graphics program)

turtle.fillcolor("darkorange")#The fill is selected from the named colours - see here

turtle.width(6)#The wirdth of the line draw is '6' - quite a thick line

 

turtle.up()#Here I start to position the turtle for the drawing of the pumpkin

turtle.goto(0,-200)

Let's begin the animation...

... and here is the final result!
