Hi all,
I just installed python 3.1.2 where I used to have python 2.6.4. I'm
working on Win7.
The IDLE GUI works, but I get the following message when trying to
open *.py files written for py 2.6
? ? ? ? The Application cannot locate win32ui.pyd (or Python) (126)
win32ui is part of the PyWin32 package. Most likely you have a version
of PyWin32 for Python 2.6 installed, you should uninstall that and
install PyWin32 for Python 3.1. Downloads are athttp://sourceforge.net/projects/pywin32/files/
You should do the same for any other third party packages that are
installed.
Moreover, when I try to open an old *.py file, I sometimes get a
message saying that the file should be converted to UTF-8. What does
this mean?
Those files contain non-ascii characters (e.g. ?, ?, ?). Non-ascii
characters must be encoded when saved using and encoding. UTF-8 is one
such encoding, and it was chosen as the default .py encoding for
Python 3.x. Those files are probably in iso8859, cp432, or perhaps
UTF-16 (aka UCS-2). You can save them in UTF-8 using your favourite
text editor, or declare the encoding so Python 3 knows it. More info:
http://www.joelonsoftware.com/articles/Unicode.htmlhttp://docs.python.org/howto/unicodeI'm also trying to use the 2to3 converter, but I cannot see where the
converted files are written to!
I think 2to3 prints a diff of the file changes to the console. The -w
command line option should modify files in place.
Thank you Alex for your detailes reply.
Before switching to Python 3.1.2 I removed all my Python 2.6 packages
(python, pywin32, numpy, wxpython). However, the removal was not
complete since some files could not be removed. Additionally, I still
see my C:\python26 directory which is suposed not to exist any longer.
If I go to the Control Panel, I cannot see any of the above suposedly
removed programs as pending of removal, so I really do not know what
more to do. I was even thinking of removing the C:\python26 directory
with the Supr key, but I always heard that it is not a good idea, the
Registry could become inconsistent. Additionally, I have not found in
my Win7 system nay utility for fixing it, should it become corrupt.
Perhaps my questions concern a bit more the Operating system (windows)
than they do python, but since I am fond of python and I definitely
would like to become somehow proficient at it, I would like to solve
the problem that I have.
I would not like to take a lot of your time, but, do you have any
hints as to what I should do to 'tune' my PC?
Thank you very much for your help.
