ASSIGNMENT #5 : The Turtle artist (with for loops and functions)

YOU NEED TO JOIN A PREEXISTING CANVAS GROUP TO BE ABLE TO SUBMIT AS A GROUP See further submission details below

Write a program which does a drawing with turtle built-in functions so that the program:

a. Includes some color, fills in some area with some color, changes the pen color in some parts
b. the turtle does at least three right or left turns
c. the pen changes from being up to down at least a couple times
d. there are at least three for-loops
e. you create at least three void (or non-fruitful) functions ( i.e. not returning any value), where the functions do drawings and/or pen movements, but do not return any values
g. The defined functions are called (used and passed arguments to the parameters as needed)
h. The program generates some random values and uses them (such as random colors)

WHAT TO SUBMIT

1. If you work as a team (of up to 2 people) you need to join a pre-existing Canvas group associated to this assignment (Group gturtle). Go to People Groups / Groups are called “gturtle– n” (where n is your group number). Both team members should join the same group. DO NOT CREATE THE GROUPS, THE GROUPS EXIST AND YOU NEED TO JOIN THEM. The two partners need to join the same group.

2. ONE PARTNER ONLY SUBMITS: the turtle program (the .py file) via Canvas

3. Everyone (regardless if you work on your own or with a partner) has to ALSO submit a separate text file where you include the names and student numbers of both team-mates and you describe how you distributed your work. Also inform the time that it took you to do this assignment, include the time of both teammates in case of working in pairs. If you worked on your own you should name this file as individually.txt, if you worked in a team name the file team.txt.

4. Additionally, if you will want to show your drawing in class (optional), submit your file in the Assignment “Showing your solutions in class”.

EXAMPLES of built-in Turtle functions and the definition of our own functions

1. Check labs exercises and examples from labs weeks #5 and week #6 (A link to the example files from those labs are also provided with this assignment description)
2. Check Canvas Home More LINKS for Turtle Built-in functions and tables for color coding

CLARIFICATIONS – READ. about importing modules and about defining your functions:

By doing so, the module name (turtle or t depending on how you imported) is global, and thus you will be able to use the module (turtle or t) everywhere (i.e. t.forward(…) ) : BOTH at the top level or main program and also inside any functions you define (with no need to include the module name as parameter to the functions).

3. Using the “import xxx as” format vs. “import xxx” format is up to you, the first format allows you to abbreviate typing when using the dot notation.

5. YOU ARE ENCOURAGED TO NOT CALL a function from another function when the first function (e.g. funA) ends, and you want to continue execution in the other (funB) function. RATHER, to accomplish that two functions are executed one after the other, the top level (or whichever level needs to execute the two functions) should call the two functions, in this example, first call funA and then call funB.

6. Name your functions and variables reasonably (to suggest their purpose).
