Re: [Tutor] Checking for Python version

Your version will fail if the person is running Python 3.0, 3.1 up

exit(Please upgrade to Python 2.4 or greater.)
This would fail on python 2.0, as version_info is not available. So
you'd want to catch that, if you want to gracefully handle ancient
versions of python. You could also just compare the version_info
tuple.
This is a bit ugly, but it works at least back to 1.5.2:
import sys
min_version = '2.4'
upgrade_msg = 'Please upgrade to Python %s or greater' % min_version
try:
min = tuple(map(int, min_version.split('.')))
ver = sys.version_info[:3]
if ver min:
sys.exit(upgrade_msg)
except AttributeError:
sys.exit(upgrade_msg)
I don't have any python 3.x systems to test though.

Re: [Tutor] Please use plain text.
bob gailer wrote: Thanks for the request for clarification. By plain text I mean: one font and one size that is readable. Most of the emails I receive appear the same in font and size, so whatever that is I like. What's readable to you may not be readable to the next person though. Most likely is that many of the posters here are not sending HTML formatted mail, and thus their messages don't contain any font or size information. That's left up to your mail client and it will use whatever defaults you have chosen. Use of very small or very large font sizes or various fonts / colors makes it hard for me to read. As I compose this in Thunderbird I see Body Text and Variable Width. But I do appreciate code in Fixed Width. I believe the best answer to this issue is to not send HTML formatted mail at all. A truly plain text email contains no markup telling anyone's email client what fonts to use. That is something that rightly belongs to each user, IMO. Most of the mailing lists I subscribe to frown upon HTML mail. I don't worry about it a lot though, as I use a console based email tool and any HTML messages that are sent are simply dumped as text for me to read. (I know many others that direct all HTML mail to /dev/null.) -- ToddOpenPGP - KeyID: 0xBEAF0CE3 | URL: www.pobox.com/~tmz/pgp ~~ I am not young enough to know everything. -- Oscar Wilde (1854-1900) pgprvwdmxDxfU.pgp Description: PGP signature ___ Tutor maillist - Tutor@python.org http://mail.python.org/mailman/listinfo/tutor

But someone who cares about windows support would have to submit patches. I don't know if Travis uses windows or not. I have submitted a number of patches to eyeD3, but I don't use windows at all myself. I can't see spending any time to support a proprietary OS. :) And, to be fair, the install process isn't really OS-specific. It works on a large number of operating systems -- just not on Windows. You know, I just reinstalled Eyed3, and compared the installed result to the six files distributed in the zipped tarfile, and they're identical except that one file is named __init__.py.in instead of __init__.py, and has two doc variables defined with templates. If you want to avoid having to install a Unix-like environment, I suggest you just 1) unzip and untar the zipped tarfile, 2) copy the eyeD3 directory from eyeD3-0.6.16/src/ to Python's Lib/site-packages/ directory 3) rename __init__.py.in to __init__.py 4) (probably cosmetic) in __init__.py, edit the lines: eyeD3Version = @PACKAGE_VERSION@; eyeD3Maintainer = @PACKAGE_BUGREPORT@; to: eyeD3Version = 0.6.16; eyeD3Maintainer = Travis Shirk tra...@pobox.com; Someone else will now explain why this is a terrible idea. I don't think it is a bad idea at all. I was going to suggest something similar. If you do that, you should be able to copy the src/eyeD3 directory somewhere in your PYTHONPATH and use it just fine. -- ToddOpenPGP - KeyID: 0xBEAF0CE3 | URL: www.pobox.com/~tmz/pgp ~~ I like this 'God'; he's so deliciously evil. -- Stewie Griffin pgpzJ8ONmIkTV.pgp Description: PGP signature ___ Tutor maillist - Tutor@python.org http://mail.python.org/mailman/listinfo/tutor

I can help if you run some sort of *nix system. If you're on Windows, then I'll have to pass as I know nothing about installing python modules on Windows. :) I read the readme, which talks about executing 'configure', but that just reports back that it is not recognized as an internal or external command, operable program or batch file. Hmm, ... batch file makes me think this is Windows. On *nix systems, you run ./configure; make; sudo make install. The ./ in front of configure tells the shell that the program you are trying to run is in the current directory. Otherwise, the shell would look for configure in your $PATH, which does not include the current directory. -- ToddOpenPGP - KeyID: 0xBEAF0CE3 | URL: www.pobox.com/~tmz/pgp ~~ Mollison's Bureaucracy Hypothesis: If an idea can survive a bureaucratic review and be implemented it wasn't worth doing. pgp8LSNYi8sv7.pgp Description: PGP signature ___ Tutor maillist - Tutor@python.org http://mail.python.org/mailman/listinfo/tutor
Re: [Tutor] MP3Info class usage
Gareth at Serif wrote: Okay, I've moved over to eyeD3.py... fif nothing else, the documentation for it's usage is far superior. However, I can't get anything to run. The help gives examples of some simple tasks, but as soon as I 'import eyeD3', not even calling any functions within it, I start getting errors such as: In eyeD3.py, the 'from eyeD3.tag import *;' line (and similar) didn't work until I removed the 'eyeD3.' part and just imported 'tag'. How have you installed eyeD3? Perhaps there's something wrong with the installation. Certainly, 'import eyeD3' should not create any errors. Then in tag.py, some of the class defs complained about undefined variables, for example 'def link(self, f, v = ID3_ANY_VERSION)' needed to have quotes around 'ID3_ANY_VERSION'. That's not what you want to do. ID3_ANY_VERSION is defined in eyeD3/__init__.py. If you quote it, you're breaking it. I'm baffled that I'm having to jump through so many hoops because I imported eyeD3... is this typical? What have I done wrong? That's hard to guess at. If you can explain what you have done and how you've installed eyeD3, that would help. -- ToddOpenPGP - KeyID: 0xBEAF0CE3 | URL: www.pobox.com/~tmz/pgp ~~ Don't look for me in daylight where robots all assemble.

Re: [Tutor] Python open of c:\ path Problem
Kent Johnson wrote:
The \ character is a special 'escape' character that is used to insert
non-printing characters into a string. \t represents a single tab
character, not the two characters \ and t.
To put an actual backslash into a string, you can either double it:
'c:\\tmp\\junkpythonfile'
or prefix the string with r to make a 'raw' string, which doesn't have
any special meaning for \:
r'c:\tmp\junkpythonfile'
While I don't use Windows myself, I'm believe that you can also use
forward-slashes as the path separator, e.g.:
junkfile = open('c:/tmp/junkpythonfile','w')
(Pardon me if I'm completely wrong.)
