[Python-3000] NameError
Ali art
I am using Windows XP professional version 2002 Service pack 3. AMD Athlon(TM)XP 2400+ 2.00GHz 992MB RAM.
I have downloaded Windows x86 MSI Instaler Python 3.0rc3 (sig) Release: 21-Nov-2008.
Control Panel -> System -> Advanced -> Environment Variables.
System Variables -> Path -> edit C:\Windows\System32\Wbem;C:\Python30
start -> programs -> python 3.0 -> IDLE(Python GUI)
-> IDLE 3.0rc3 -> File -> New Window -> i wrote "print('Hello World')" without qutes
-> File -> Save -> Python30 -> i gave file name "helloworld.py" without qutes
-> and saved -> and closed file and python shell
-> and then start -> programs -> python 3.0 -> Python (command line) ->
Python 3.0rc3 (r30rc3:67313, Nov 21 2008, 07:14:45) [MSC v.1500 32 bit (Intel)]
on win32
Type "help", "copyright", "credits" or "license" for more information.

-> i wrote "helloworld.py" without quotes -> it gives NameError ->

You should ask these kind of questions in the Python general list:
http://www.python.org/mailman/listinfo/python-list
This Python-3000 list is about developing Python 3 *itself*, not
developing *in* Python

You do know you can run the file from within IDLE by just pressing F5, right?

No! Wrong! See below.

As I believe someone pointed out earlier when you previously asked
this question on one of the other mailinglists, to do what you want to
do, you should:
1. Go Start -> Run, enter "cmd", click Run, to open the DOS shell.
2. cd to whatever folder helloworld.py is located in
3. running the following command in the terminal window: python helloworld.py
Python's "shell" is an interactive interpreter of Python *code*, and
is NOT used to run python script *files*, at least in the particular
way you're trying.
When you enter "helloworld.py" at the Python interpreter prompt,
Python is not trying to run the file "helloworld.py"; it's looking for
a variable named "helloworld" to then find the "py" attribute of (i.e.
the dot is an operator in this instance). Since there's obviously no
such variable, it's raising a NameError exception.
For simplicity, I'd recommend just running the script directly from
IDLE as I explained above.
Finally, I echo the comment that your question is completely offtopic
for this mailinglist, which is about developing Python 3.0, not using
Python 3.0 (unless you found a bug, which is not the case here).
Cheers,
Chris
