Is it possible to minimize a python program to the task tray area of the taskbar in Windows95/98? Bob pop3.rma.edu

parsing?
by Ingo July 1, 2001

July 1, 2001

I'm tying to make something that can read some values and functions from a file and then use these to create a parametric surface in triangles to be rendered by POV-Ray. The triangle generation isn't the problem, but reading the functions into the program. If I have a line read from a textfile that says: u=2 how do I manage to make a value u=2 available to the program, that read the textfile, so it can do some calculations with it? The same, but now for a function: Function Fx(u,v,R)=R*sin(u)*cos(v) How do I make the above available in the program as if the below was part of it? def Fx (u,v,R): x=R*sin(u)*cos(v) return x TIA, Ingo -- Photography: http://members.home.nl/ingoogni/ POV-Ray: http://members.home.nl/seed7/

OOP with Tk/Tkinter
by Brendon June 30, 2001

June 30, 2001

Now that i've been through the tutorial on http://www.crosswinds.net/~agauld/ I'm not sure where to go next. I want to learn more about GUI object orientated programming with Tk/Tkinter. I've only be able to find two tutorials for Tk/Tkinter and both were not OO. Any suggestions anyone?

OT: HTDP

As the "general programming question" thread revealed, the htdp.org people are having trouble with their domain and "How To Design Programs" is temporarily unavailable. I had snarfed the site a while ago and I've put the tarball on my personal site at http://members.home.net/rufmetal , which I'll leave up until the official version of the book comes back online. Hope that helps those who are interested. - Chris

---------- Forwarded message ---------- Thanks, After changing the slice it did the trick. Although I have been a user of unix systems for a couple of years, I only recently switched to linux for my home computing. I didnt know about the ifconfig command. Needless to say, it looks like I will be having a look at the os module tonight. > This is the first thing that came to my mind, you might have to replace > the interface to match with yours and change the slicing but you > should still get the idea of what I'm doing, just a cheesy os.popen :) > > >>> import os > >>> ip = os.popen('/sbin/ifconfig eth0 |grep inet').read()[20:-37] > >>> ip > '10.0.1.3 ' > > > > -- > DEV > > > On Sat, 30 Jun 2001, pd wrote: > > > Hi, > > I dont think I made myself clear when I posted my original > > message.

Any ideas? Simon, I just executed the lines of code in PythonWin (ActiveState build 203) without the trailing slash and received the following >>> import urllib, pprint >>> page = urllib.urlopen('http://www.python.org') >>> data = page.readlines() >>> pprint.pprint(data) ['<HTML>\n', '\n', '\n', '\n', <SNIP> Or, IOW, worked for me. Possible transient error at python.org? Or that you're using an earlier version of Python? Bill

Getting my IP
by pd June 30, 2001

June 30, 2001

Hi, I dont think I made myself clear when I posted my original message. The purpose of the script is to post the ip address of my home pc to a webpage running on a remote host. This is what is going on. 1. I execute the script on my home pc. 2. The script fetches a html page from the web. 3. It reads the html page into a list. 4. It searches the list for a specific point () . 5. It inserts my IP address into the list after the marker. 6. It writes the processed list to a html file. 7. It sends this modified html file via ftp to my webpage. Any details that I need to enter are stored inside a config file which the script accesses It is almost done except I cannot figure out how to find out what *my* ip address is. Up until now I have just included it as a variable (myIP = 218.13.23.45) for testing purposes. When I use the following line of code, I get my loopback address, as opposed to my dynamic IP address. >>> from socket import * >>> gethostbyname(gethostname()) '127.0.0.1' I do not know much about networking/programming/sockets so detailed answers will be greatly appreciated. I am using python 2.0, on a linux box.

Getting my IP

Hi, Im writing a script that posts IP number to a page on my website. This script is nearly complete except I cannot figure out how to actually get my IP address. I have tried using the socket module, but it appears that this justs takes a look in my /etc/hosts file. What I need is my dynamic IP that gets assigned every time I connect to the net. Python 2.0 (#1, Apr 11 2001, 19:18:08) [GCC 2.96 20000731 (Linux-Mandrake 8.0 2.96-0.48mdk)] on linux-i386 Type "copyright", "credits" or "license" for more information. >>> from socket import * >>> gethostbyname(gethostname()) '127.0.0.1' >>> gethostbyaddr(gethostname()) ('localhost.localdomain', ['localhost'], ['127.0.0.1']) >>> gethostbyname('kaneda') '127.0.0.1' >>> getfqdn() 'localhost.localdomain' >>> gethostnyname('kaneda') [pd@localhost pd]$ cat /etc/hosts 127.0.0.1 localhost.localdomain localhost 127.0.0.1 localhost.localdomain kaneda [pd@localhost pd]$
