[Visualpython-users] VPython-Win-Py2.4-4.beta2.exe

[Dr P H B. <P.H...@bh...>]

I have downloaded VPython-Win-Py2.4-4.beta2.exe (but visual.version = (4,
'beta1'))

My operating system is windows Me (update from windows 98)

When I import visual as [from visual import *], dir() generates error
message : see below
but if I import it as "import visual" dir(visual) works ok

When I type ball = visual.sphere() I get message from PythonW :
PythonW has caused an error in OPENGL32.DLL

Help, please

Thanks for the report. On Windows XP on a laptop I can reproduce the 
dir() behavior(str object not callable). When I try visual.sphere() I 
get a different problem: NameError: name 'visual' is not defined.

There seem to be various screws loose in the Windows version, and it's 
useful to have a catalog of these loose screws.

There is a local variable named dir defined in
site-packages/visual/__init__.py (on or about line 38).  Rename it to
_dir, and this won't be a problem.  This has been fixed in CVS, and will
be applied to the next release.

This was my mistake - loops do not have their own scope (or something
like that), and I had forgotten that property.
