I'm glad turtle graphics intersected my thinking re extended precision
decimals (Decimal type) on edu-sig just now.
I've updated my tmods.py to contain a turtle rendering the plane-net of a T-mod:

Hello Brian,
I think the most natural use of the if statement (using turtle
graphics) occurs in recursive functions drawing trees,
fractals and the like. This is well known from Logo, where
recursion is the canonical way of doing repetitions. (But
note, that Logo has tail recursion optimizaton!)

What's the best way to get the fractional part of a real? The two
ways I can see are r % 1 and r = int(r), but both seem a bit hokey.
Is there something more straight-forward that I'm missing, like
fraction(r)?

For my part, i reach to this rather complicated code:
# --
def comaSep(z,k=3, sep=','):
z=z[::-1]
x=[z[k*i:k*(i+1)][::-1] for i in range(1+(len(z)-1)/k)][::-1]
return sep.join(x)
# Test
for z in ["75096042068045", "509",

I fixed this to produce the actual image I'm looking

use up() & dowm() in place of penup(), pendown() and

I'll be posting a followup report later.

Hi Ram,
that's indeed a nice starting point for kids to doing turtle graphics,
although currently it seems to implement only a very small subset of
Python's turtle module's capabilities, even less than those of the old
turtle module (that shipped with Python upto 2.5).

Hello,
I wanted to announce that I have just released my little side project,

Here is its website:

Its goal is to be the lowest-threshold way to learn (or teach) Python.
You can read more about it and download it on the website.

Hi all,
A few days ago I've created a repository of turtle graphics
demos/applications, that use Python's new turtle module.
You can find it at at google code:

There are two versions of the collection: one for use with Python 3.1
and one for use with P
