On the site

there are several scripts for fractals. See page five.
These begin

This fails in my python 3.1.2
Google reveals PIL is Python Imaging Library from

Have recently moved from XP to Ubuntu Linux.
Successfully installed Python 3.1.1 in the Ubuntu 9.04
release on my desktop.
Problem is the python interactive terminal >>> .
Many of the keys now do not work.
eg pressing left-arrow yields ^[[D
right-arrow ^[[C
I've been given a MAC AIR laptop with OS X 10.6 "Snow Leopard".
On my desktop I dual boot with XP - Ubuntu and have Python on both.
Unfortunately all my Python programs are written on Windows XP and
I heavily rely on WConio for console I/O.
Called Apple tech support. The technician had never heard

The WConio console module produces different colors, sometimes quite

I'm using Python 3.0 with the corresponding WConio on XP.

Thanks Mark & Rhodri. Neither works.
I'm using Notepad2 as editor. Don't use the tab. Each space
counted with spacebar & recounted. Rewrote the block from
scratch as new script and eliminated the print line in the loop.
Now no error message, but it will go on forever despite repeatedly

In my programs the 'break' fails to work. I've studied the docs for
3.0 and Programming in Python, neither of which are illuminating.
Simplest example :
while True :
num = int(input())
print(num)
if num == 0 :
break
print('done')
SyntaxError : invalid syntax( pointing t

When I open python.exe to the console or "interactive window" and

script in the same session. eg I run the script alphasort once fine :
