What I like about Slackware/python is that you get the full python 
distribution. My last experience with Debian & subordinates was that 
only the "core" python was included with the distribution, and a bit of 
hunting was required to get Tkinter working. Maybe this has improved in 
the last year or two?

Tkinter from Vis. BASIC

[Terrance N. Phillip]

In VB, an easy way I indicate progress is something like
do while 
lblNotify.foreground = randomcolor
 lblNotify.refresh   <---
 
  loop

I want to do the same thing in Python/Tkinter:

 # Wait for network to recognize the workstation:
 while os.system("slist") != 0:
 self.notify["fg"] = randcolor()
 # how do I refresh label l3 at this point?
 time.sleep(3)

I've tried self.notify.grid() (I'm using the grid geometry manager 
throughout), but that didn't work, and there is no redraw() or refresh() 
method that I can see.

Thanks. I did a dir(label_object) and saw update() and 
update_idletasks(). updeate() seems to do the trick.

System Independent Wallpaper Changer

[Terrance N. Phillip]

This is what I've got... the code should work on a typical Windows 
system, I think...

import os
import random
import time

# I'm not sure what to expect for Win98, WinME, etc. I've
# only tried it with xp...
if os.name in ['nt', 'win98', 'me']:
 osWindows = True
 import ctypes
 import win32con
 import Image
 pth = 'c:/path/to/wallpapers'
else:
 osWindows = False
 pth = '~/path/to/wallpapers'

picfiles = os.listdir(pth)

while True:
 jpg = random.choice(picfiles)
 if os_type = 'W':
 bmp = 'c:/wallpaper.bmp'
 Image.open(pth+jpg).save(bmp)
 cs = ctypes.c_buffer(bmp)
 ok = 
ctypes.windll.user32.SystemParametersInfoA(win32con.SPI_SETDESKWALLPAPER,0,cs,0)
 else:
 pass
 ' set kde wallpaper to jpg  <- *** ---
 time.sleep(60)
=

I've done some searching, and can't seem to find a programatic way of 
getting *** that to happen.

Thanks for any advice.

Nick.

That helps very much, thank-you! And sorry to previous posters: yes, 
indeed, I changed naming conventions part way through--you got an 
intermediate version.

Re: Problem loading a file of words

[Terrance N. Phillip]

Kevin,
I'm pretty new to Python too. I'm not sure why you're seeing this 
problem... is it possible that this is an "out-by-one" error? Is 
zymotechnics the *last* word in dictionary.txt? Try this slightly 
simplified version of your program and see if you have the same problem

def sort_string(word):
 '''Returns word in lowercase sorted alphabetically'''
 return "".join(sorted(list(word.lower(

dictionary = {}
f = open('/usr/bin/words') # or whatever file you like
for line in f:
 sline = sort_string(line[:-1])
 if sline in dictionary:
 dictionary[sline].append(line)
 else:
 dictionary[sline] = [line]
f.close()

lookup = raw_input('Enter a scrambled word : ')
while lookup:
 try:
 results = dictionary[sort_string(lookup)]
 for x in results:
 print x,
 print
 except:
 print "?"
 lookup = raw_input('Enter a scrambled word : ')


Good luck,

Nick.

Parallel arithmetic?

[Terrance N. Phillip]

Given a and b, two equal length lists of integers, I want c to be 
[a1-b1, a2-b2, ... , an-bn]. I can do something like:

c = [0] * len(a)
for ndx, item in enumerate(a):
 c[ndx] = item - b[ndx]

But I'm wondering if there's a better way, perhaps that avoids a loop?

Nick.

(I seem to recall from my distant past that this sort of thing was dead 
easy with APL... c = a-b, more or less.)

Re: Parallel arithmetic?

[Terrance N. Phillip]

Thank-you very much for all the excellent replies. I'm thinking of using 
this to determine if a sequence is a "run" (as in a card game). If I've 
got a sorted hand [3, 4, 5, 6, 7], then I know I've got a 5-card run 
because [4, 5, 6, 7] - [3, 4, 5, 6] == [1, 1, 1, 1]. I want to avoid 
something like
if h[0] == h[1]-1 and h[1] == h[2]-1 ...
