RE: [Tutor] What am I doing wrong...
The basic problem is you never told Python to DO anything except define what it would do if anyone asked it to. If you add the line "main()" to the bottom you'll get your message printed. I'm not sure if this is your code or my mail agent (outlook) but as you can see below there's a space between the function name (main) and the parenthesis. I don't believe that's supposed to be there. Good Luck.

Anyway, I got to the Using Environment Variables chapter that is in this page: http://www.oreilly.com/openbook/cgi/ch02_02.html. This is UNIX environment variables (as I understand), and I guess they will not work on Windows... So what are the Windows environment variables and how can I use them with python (like any other variable or in a special way?) ? Thanks! Morning Mark, Happy New Year, Merry Christmas, and a jolly Winter Solstice Season! Whenever you're talking about how to do something in Windows it REALLY helps when you include WHICH windows you're working with. I believe the following will allow you to manipulate windows environmental variables. If anyone sees I'm wrong I know they'll speak up. The "set" command when run in a command window without parameters lists your current environmental variables. You can also use it as: c:\> set hello=Hi there Mark which will set the variable "HELLO" to "Hi there Mark". c:\> echo %HELLO% or c:\> echo %hello% will now print "Hi there Mark" without the quotes. Note that quoting, case sensitivity, and white spaces can all react differently under windows than they do in Python. If you need to set an environmental variable to a value every time you start windows then you can either store the above set command (no spaces around that "=" remember) in the autoexec.bat file or on Windows 2000, XP and (I believe) NT you can right click on the desktop icon "My Computer" and select "Properties". Now you're looking for the "Advanced" tab and the environmental variables button in Windows 2000. I THINK it's under the "System Performance" tab and advanced button in XP and you'll have to dig in NT. I'm not sure you can do this here under the win 95/98/ME family. Sorry, right now the only windows product I'm running at home is 2000. You can also set Windows environmental variables from within your python script of course. FYI being a coward myself before I go changing my setup I like to document things. Say running "set > Environment-Before.txt" in a nice safe directory. This will output your current setup so if things get weird you can at least bring things back to you starting point.

Hi Mark,
You'll want to grab a "Python DB API" module for MySQL. The best one I've
seen for MySQL is 'MySQLdb':
http://sourceforge.net/projects/mysql-python
and you should probably grab that for your system. It should come with
some examples to help you get started.
Python.org has a section on Python's database support:
http://www.python.org/topics/database/
with some documentation. There used to be a tutorial linked from Linux
Journal there, but it's now restricted to subscribers! *g*
Here's an example program just to see how the pieces fit together:
###
import MySQLdb
connection = MySQLdb.connect(db="magic", user="dyoo",
password="abracadabra")
cursor = connection.cursor()
cursor.execute("""select name from cards where
tournament_type = 'restricted'""")
for (name,) in cursor.fetchall():
print name
cursor.close()
connection.close()
###
I hope this helps you get started!

Does the style of coding Python engenders suit the Perl environment in anyone's experienc? AFAI can see there is no real 'style' to Perl, apart from white noise of non alphanumeric characters. Just wondering if I should bite the bullet and code from scratch in Perl, or if my Python - Perl is Ok. Two codes are here - Python http://www.rafb.net/paste/results/BVaym940.html Perl http://www.rafb.net/paste/results/LromA876.html [OT begins] By the way, I'm only learning Perl because I need to script some routine HTML maintenance, and I can't be bothered applying to head office IT for an install of Python, as the justification involved is ludicrous, especially considering that my role as defined does not include scripting. First impressions of Perl - 1) I'll use Perl for the regex stuff from now on, Perl is obviously built for this. 2 ) There's More Than One Way To Do It makes debugging hard - i.e. close INFILE; & close (INFILE); are both valid. I like one syntax, cos it's easier to remember. 3) Some stuff is counter-intuitive - $lenOfModList = @moddirList is the Perl equivalent of lenofModList = len(moddirList) @someArray = (@someArray, $newValue) is the same as someArray.append(newValue) I couldn't figure this one out until I read that Perl automatically flattens lists. Also, why doesn't if ( not $d eq "a" && not $d eq "c") evaluate to true for $d = "b" when if (not $d eq "a") evals to true and if ($d ne "a" && $d ne "c") evals true also? What's with that? 4) WHAT IS WITH THE STUPID SYMBOLS EVERYWHERE LARRY??!! I'm not referring to the $ & @, I can see how they could be useful, although with a list - @dude = (1, 2, 3), to obtain the 2nd value I would expect $d = @dude[1], not $d = $dude[1], that's counterintuitive also. Oh, no, what I'm referring to is stuff like @_, and @!, and @indexFile = to read a whole file, and this - I hate Perl for this - open OUTFILE, ">c:/python23/j/index.htm" What's the difference between open OUTFILE, "c:/python23/j/index.htm" and open OUTFILE, ">c:/python23/j/index.htm" ? The first will open index.htm with the handle OUTFILE, to read... The second will open index.htm with the handle OUTFILE to write!. Of course, the documentation I had didn't mention that. It just said to open it and use print FILEHANDLE $value; to write. Oh no, I had to find a CGI Perl tutorial, which mentioned using &lst; to open and &gst; to write (or something), which I guessed as lesser/greater than. Why is the read/write modifier part of the filename??? Why is it a > ? In my opinion, there's only one place a > sign should be, in an inequality test. So, Perl in my opinion - great for regexes obviously based around *nix conventions. Big hodge-podge, oozing with inconsistency. I'd hate to work collaboratively on a Perl project.

Hi all,
This is slightly off topic, but I've noticed a lot of people are using
gmail accounts to post to tutor and I just wanted to share a useful
trick I just learned for making gmail display and edit mail with a
monospace rather than proportional font. I'm sure anyone who's tried
it agrees that significant whitespace means that python and
proportional fonts don't play well together...
Basically, you need to get your browser to override the stylesheet of
the page with the following snippet of css:
div.msg div.mb, .cm, .tb {
font-family: monospace !important;
font-size: 12px !important;
}
In Firefox, you add it to the userContent.css file in your preferences
(you'll probably have to create this, see
http://www.mozilla.org/support/firefox/edit). With Safari on MacOSX
you make a css file anywhere you like (I used
~/Library/Safari/MyPrefs.css), add this snippet, and then select the
file from the "Advanced" tab in Safari's Preferences. I don't know
about other browsers, but the same sort of thing is almost certainly
possible.

Re: [Tutor] Python Resources
Greg, Thanks for taking one for the team! How about some OS specific resources like the Active State (I think I have that right. At work so I can't check) stuff for windows/com and the debian-python mailing list that came up the other day. I even ran across some AS-400 python stuff a while back. Python is cross platform but there are platform specific issues and communities that can help with them. Just a thought. Thanks for being out there and making us look good.

The editors asked for about half the article dealing with using Python and the other half giving a short tutorial. They also asked for three "sidebars"; I'm going with Tim Peter's "Zen of Python" for one, a comparison of "Hello, World", in C, C++, Perl, and Java in the second, and for the third I would like to list some resources. I have the Python home page, "Dive Into Python", the Python Gems" page, but would like to ask what resources would any of you suggest? I'd like between 5 and 10, with a short description of each. The article emphasizes the simple syntax of Python and the friendliness of our community. It encourages anyone interested in learning to subscribe to this mailing list and ask questions (though I do caution them not to submit their homework simply to get a solution). I have asked two people to review the paper from a "Python" perspective to make sure I have not mis-represented the language (I'm sorry about the delays, Steve, but the paper is coming!). If any of you would like to review it, I would be happy to send you a copy, too. I have about a week before submission.

Re: [Tutor] Quickest way to find a folder on windows
Since the "My Documents" folder can be re-named you need to search the registry to see what the user's "my documents" folder is. I'm not sure what domain constraints might do to this setting. Perhaps the most efficient method if you were just interested in the current user's "My Documents" directory would be to determine the current value of the %HOME% variable.

Re: [Tutor] Handling binary file
Julie,
I've had to work with some binary files with 3 byte data
types. They were generated by an application coded in Business
Basic. Like you I grabbed it as bytes and converted. For clarity's
sake I used powers of 2 instead of hard coding the numbers. 2^8 makes it
pretty obvious why you're multiplying by 256 IMHO. Look out for negative
numbers though. May not be applicable to "number of seconds" but as a
general rule watch for it. Incidentally when I had to read the same data
with VBA I used the same technique to reverse the byte order from Unix to
Windows. Worked just fine.

I have opened a file in binary
mode. The 9th,
10th and 11th bytes contain the time in
seconds. In order to
get this value in decimal I did the
following:
timeinsec = bytes[9] * 65536 + bytes[10] * 256 +
bytes{11]
Would someone please advise if there is a better way to
do this?

Really, it's so simple it's hard to come up with directions. Just do
