Fractals (Julia set)

I have been playing around with generating fractals in Scratch.
This is a Julia set image I have made. I can post the code if anyone is interested.

Re: displaying long need help with floating point numbers

Thanks BlackJack - I think it was the pow bit that was the main stumbling block Yeah - I changed it to 50, just because I was trying out a few changes and wanted each run to be a bit quicker.

Re: displaying long need help with floating point numbers

Thanks BlackJack, I have had another go at doing this using Decimal. I must have missed something important, because it doesn't make any difference. This is what I came up with: # pi.py - arctan(1) * 4 = pi from math import * from decimal import * getcontext().prec = 50 def arctan(n): """Uses Gregor...

displaying long need help with floating point numbers

Hi, I have written a little program that works out Pi using atan. I can get it to give me about 50 decimal places, but I really don't understand the "Decimal" module. If anyone can give me some tips on how to get a more precise result, I'd appreciate it. Here's my code: # pi.py - arctan(1) * 4 = pi ...

Re: Run my python prog without terminal

The way I do it is to add a line like this to the start of the python code:

Code: Select all

#!/usr/bin/python3.1
Then you will need to make the file executable:

Code: Select all

chmod +x my_file.py
After this, clicking on the file should run it without a console appearing.

Re: lisp and scheme

Just learning some bits of Scheme at the moment. Here's a little program that I wrote from scratch. You give it an integer and it hands you back a list of random numbers between 1 and 12. ; get_nums. Takes an integer and returns a list of that length, ; populated with random numbers (1 - 12) (define...

Re: Scheme implementations

Since I've started this thread, I thought I'd post up the link to the MIT Scheme binaries.
This took over 24 hours to build on the Pi, so if you want to try it out this could save you some time.

That looks like it's a python 2.x script (no parentheses after print).
Did you run it with Python 2 or 3?
Try

Scheme implementations

Chicken and Bigloo are available in the repos, but I also fancied having a look at Gambit (which does nice things like flashing parentheses as you close them) and Scheme48.
I've compiled both and here are the binaries if anyone wants to try / test them.

Re: Running .py file from Python3

It might help if you can share your code.
Depending on what the program does, it might help to add:

Code: Select all

input()
To the end of your program - then the window should wait for you to press enter before quitting.
