Re: [Tutor] (no subject)

I'd have rather you top-posted, then I wouldn't have wasted 30 seconds
scrolling past a bunch of irrelevant crap that I just gloss over
anyway.
If I want context I'll read the previous messages in the thread.
but that's just MHO.

Hi
I thank you for your prompt response. I am using WINXP.  Possibly programs 
written for Python 3 may not work in Python2 as informed by you due to 
syntax unmatch. However when I try hello.py on both Python2 and python3, 
it works on Python2 but does not work in Python3. Here is what I get

then followed by when OK prompt is clicked. This means that irrespective 
program code Python3 does not execute hello.py while python2 executes. 
This I suspect some setting error?

Here is what I got when I run the same program on Python2

Please advice. I give below sourcecode of hello.py
#! /usr/bin/env python3

print("Hello", "World!")
