1. Fractals help

2. Overview Last lecture: Modules Variable scope Packages This time
Work through results from the lab
Additional problems

3. Task 1 Create a directory to store you new modules and packages
Add the directory to your module path using the .bashrc file
Write a module that when given a 2D array of 1 and 0s saves a pbm file to disk

4. Mandelbrot set: plotting module

5. Using the plotting module

6. Putting the module in the path
On the Linux terminal:
mkdir ~/python_bin
export PYTHONPATH="${PYTHONPATH}:/home/users/tom00/python_bin"
cp mypbm.py mypbm_backup.py # save a backup just in case
mv mypbm.py ~/python_bin
Make sure you do not duplicate modules. If you have one
in your working directory and one in the PYTHONPATH which is the system using?

7. The Mandelbrot set

8. Koch snowflake
Part 1 Koch curve

9. Order 2 Koch curve

10. Order n Koch curve

11. Snowflake

12. New task: Julia Sets For each c a Julia Set can be constructed.
The Mandelbrot set acts as an index for the Julia set
Based on the Mandelbrot code
calculate the Julia set for c= i i i i

13. Extra problems
Write a code to evaluate the area of the Mandelbrot and Julia sets
Add colour/grey scale to the Mandelbrot plot.
The Julia set is not always connected, write a code to calculate a histogram for the size of domains.
