[Tutor] Unable to run Programs on WINXP using Python3

Wed May 12 05:31:19 CEST 2010

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 programs written for Python3 in Python3 
it first comes out with a pop up message "C:\python31\python.exe is not a 
valid Win32 application"  When I click OK prompt on pop up message then on 
dos box it states   "Access is denied."  I tried various types such as 
python, python.exe and without these two also but same pop up message 
comes out. Please advice.

Regards,
Siva

(1. Please don't top-post.  It gets everything out of sequence, and is the 
wrong convention for this forum
2. Be sure and do a reply-all, so that the message goes to the forum.  I'm 
not here to give private advice.
3. Use your editor's reply-quoting so that we can tell who wrote which 
parts.  Normally, you'll see that as either a leading ">" character or as 
a "!" character.  And one can tell which parts were written by whom by 
counting the number of those at the beginning of each line)

For my real response, see the end of the message, where it belongs.

Thank you very much for your response. I think I have problem with both 
Python23 & Python31. Please help.

Python23 : The program works but programs written by Mark Summerfield in 
his book Programming in Python3 does not work.
Python 31: When I run this program it says in the pop up window "
C:\py3eg\csv2html1_ans.py is not a valid Win32 application" and on the the 
dos box it says Access is denied.
Below is the dos box contents

C:\>cd python31

C:\Python31>python C:\py3eg\quadratic.py
Access is denied.

C:\Python31>python C:\py3eg\hello.py
Access is denied.

C:\Python31>python.exe C:\py3eg\hello.py
Access is denied.

C:\Python31>cd..

C:\>cd python23

C:\Python23>python.exe C:\py3eg\hello.py
('Hello', 'World!')

C:\Python23>python.exe C:\py3eg\print_unicode.py
Traceback (most recent call last):
 File "C:\py3eg\print_unicode.py", line 30, in ?
   print_unicode_table(word)
NameError: name 'print_unicode_table' is not defined

C:\Python23>python.exe C:\py3eg\quadratic.py
 File "C:\py3eg\quadratic.py", line 14
   except ValueError as err:
                      ^

Hi
I am learning Python. When I tried to run any of the program for example   

csv2html1_ans.py it displays the following message. This error is coming   

on both Python24 & Python 31. That is whether i give the any one of the 
following command

COMMAND GIVEN
1.C:\python24\python.exe C:\py3eg\quadratic.py
2.C:\python31\python.exe C:\py3eg\quadratic.py

A message below appears with the program name. Please advice me how to     

get   
over from this issue
ERROR MESSAGE

Please copy and paste the actual contents of your DOS box, rather than 
paraphrasing.  COMMAND hasn't been the normal shell name since Win95 days. 
 You can't use numbers in front of commands in any shell I've used.  The 
error message refers to a different file than anything you specified in 
your commands.

What OS are you using?

Again, what OS are you using?

I have no idea what the pop up comes from, but I suspect you have some 
non-trivial code in that python program, perhaps that creates a gui.  Is 
there any tkinter stuff in it?

As for "Access is Denied", it usually means you tried to access a 
non-existent drive, or one which isn't currently mounted.  For example, 
referencing your CD drive with no platter in it.

I don't know why "print_unicode_table" is undefined, but apparently you're 
missing some code.

And the except clause changed between 2.x and 3.x, so you need to change 
the syntax to match the particular interpreter you're using.  They're not 
compatible, although there's a utility to convert from 2.x to 3.x, I don't 
think there's anything that reverses it.

I'd suggest picking one version, and using only books and references that 
are compatible with it till you're comfortable with the language.
