I ask this, because these two show different behaviour.
i use IDLE, in Python 3.0
i have a problem with python 3.0 graphics module:
no problem while importing the module
import turtle
but when i issue any command like:
t = turtle.pen()
After performing this command you should be able to observe
a blank window with a tiny black arrow - it's the turtle
yes, i can see it but each time i try to get into that window, the
mouse pointer switch to the hourglass look and i cannot do anything
over the windwow;
moreover, if i try to click or move it, WS Xp tells me the program
pythonw.exe is not responding
pen() is a function in the module turtle. It returns a dictionary
of the attributes of the turtle's pen. Have a look at it:
print(t)
{'pensize': 1, 'resizemode': 'noresize', 'pendown': True, 'fillcolor':
'black',
'speed': 3, 'shown': True, 'outline': 1, 'tilt': 0.0, 'pencolor': 'black',
'stretchfactor': (1.0, 1.0), 'shearfactor': 0.0}
yes, i get a very similar answer
t = turtle.forward(60)
nothing appears on the screen, only a blank window, with nothing inside;
may you give me some hint ?
What happens if you do this?
from turtle import *
for i in range(4):
forward(100)
left(90)
as i wrote before, i can see the arrow inside the graphic window but i
cannot do anything inside it, i mean i cannot move or resize the
window etc.
anyway, yes i can see the arrow moving and drawing the square correctly
ps: i'll answer to your other mails also, thank you very much Gregor

That's certainly true, and it was the reason for introducing Idle's feature to execute scripts in their own subprocesses with Python 2.3 Despite of this I like to use Idle when working interactively with the turtle module and also when developing small programs as it is much more comfortable than a cmd-shell window. But I reglularly run them (during development) from the 'normal' Idle (or from a cmd-shell) to assure that effects like those you mention below are not present.

Hello Roberto,
First question:

I ask this, because these two show different behaviour.

'speed': 3, 'shown': True, 'outline': 1, 'tilt': 0.0, 'pencolor': 'black',
'stretchfactor': (1.0, 1.0), 'shearfactor': 0.0}
t = turtle.forward(60)
nothing appears on the screen, only a blank window, with nothing inside;
may you give me some hint ?
Hmm, in my window the turtle goes 60 pixels to the right and draws a
black line.
The statement
t = turtle.forward(60)
doesn't make much sense, though. It calls the forward() function of the
turtle module and names it's return value t. Alas:
print(t)
None
Not really useful.
turtle.forward(60)
is sufficient.
What happens if you do this?
from turtle import *
for i in range(4):
forward(100)
left(90)

Gregor
