Available in Tkinter from Python 2.7 and 3.1 or whatever. And there is a lot of missing functionality. This is still true although Tix addresses the biggest gaps - but is sadly lacking documentation - you have to use the Tcl/Tk docs :-( (I keep intending to do a write up on Tix but other things get in the way!) And there are other bolt-ons too such as PMW. I'm getting into wxPython at the moment, and I have to say it's at least worth a look. It's also available for every platform (but doesn't come with Python), and is far more complete, and just about as easy to use as Tk, but looks a lot more polished. wxPython is definielt more powerful and in particular has support for things like printing and drag n drop which are missing fromTk. There are other toolkits with their advocates as well, of course, but if someone were just starting out with Python GUI programming, I'd recommend looking around at your options before starting with Tk. I'd still advocate Tk because a) It comes with Python so is standard b) It is also the standard GUI in Ruby, Perl and Tcl so once learned is oportable c) It is best documented with many books etc featuring it d) It is easy to learn the basic GUI principles that are valid in any Framework (a bit like learning Python is good becauise it helps you learn other languages) HTH, -- Alan Gauld Author of the Learn to Program web site http://www.alan-g.me.uk/ ___ Tutor maillist - Tutor@python.org To unsubscribe or change subscription options: http://mail.python.org/mailman/listinfo/tutor ___ Tutor maillist - Tutor@python.org To unsubscribe or change subscription options: http://mail.python.org/mailman/listinfo/tutor
[Tutor] Any
Hi all, I was just wondering if anyone here can recommend any freeware program that has been written in python and for which the source code is available. Basically I just want to see a program that does something relatively simple and straightforward, but something that is real world, I mean something that people actually use, hopefully something that comes with it's own installer and GUI. I'd like to try out using the program as an ordinary user and then I want to look at the source code to see how it's been achieved. Any ideas or suggestions?

[Tutor] How to get ipRouteTable from Cisco router?
Hello!
I want to get route tables from Cisco routers in the network. What i
have:
import re
from pysnmp.entity.rfc3413.oneliner import cmdgen
s = r'(%s)' % ('(?:(?:25[0-5]|2[0-4][0-9]|[01]?[0-9][0-9]?)\.)\
{3}(?:25[0-5]|2[0-4][0-9]|[01]?[0-9][0-9]?)')
pattern = re.compile(s)
file = 'routers.txt'
s = open(file).read()
i = 0
router_list = []
while True:
match = pattern.search(s, i)
if match:
router_list.append(match.group(1))
i = match.end() + 1
else:
break
class router:
def __init__(self, who):
self.name = who
routetable = {}
router1 = router(router_list[0])
cmdGen = cmdgen.CommandGenerator()
errorIndication, errorStatus, errorIndex, varBindTable =
cmdGen.nextCmd(
cmdgen.CommunityData('test-agent', public, 0),
cmdgen.UdpTransportTarget((router1.name, 161)),
(1,3,6,1,2,1,4,21,1,1))
if errorIndication:
print errorIndication
else:
if errorStatus:
print '%s at %s\n' %
(errorStatus.prettyPrint(),varBindTable[-1][int(errorIndex)-1])
else:
for varBindTableRow in varBindTable:
for oid, val in varBindTableRow:
print varBindTableRow
Result:
Code: Select all
[(ObjectName('1.3.6.1.2.1.4.21.1.1.0.0.0.0'), IpAddress('0.0.0.0'))]
[(ObjectName('1.3.6.1.2.1.4.21.1.1.10.9.0.0'), IpAddress('10.9.0.0'))]
[(ObjectName('1.3.6.1.2.1.4.21.1.1.192.168.1.0'),
IpAddress('192.168.1.0'))]
How can i get IpAddress values from this list and put they in the
dictionary? Or may be there is much better solution?

The Reddit website is written in Python, as is the EVE Online massive multiplayer game, although I doubt the source code for them are available. Actually, Reddit has made it's source available and has included a HOWTO install Reddit on your webserver. There is a Google Group reddit-dev for this purpose, as well.

My guess, from looking at what you have there, str(varBindTableRow[1]) should
get your IP address in a string format. In any case the varBindTableRow[1] will
contain the IpAddress object(?) that is displayed in the lists.
HTH,
Wayne
Results are:
1. print str(varBindTableRow[1])
IndexError: list index out of range
2. print str(varBindTableRow[0][1])
АЁ
3. but for ipRouteIfIndex, i have
print str(varBindTableRow[0][1])
0
0
1
So, it works for IfIndex, RouteType, but not for Dest, Mask and NextHop as they
return ip.
Thanks indeed.

BJ_Game will calculate the number of players and asks if ask BJ_Deck if it can support that much player.

[Tutor] Boa Constructor list control
Hello, I am just learning how to use Boa Constructor to make GUI apps, and am having some problem with understanding the list control. The list control has a property called columns, but I cannot figure out how to add columns, and specify names for them. When I click the column property a small window opens up with it's title set to col1 something with the word Name in a label on it. Subsequent clicks on the column properry of the list control just brings this little window up again. I cannot change the text in the label of that small window to the name I want for a column, and I cannot figure out how to add more columns to the list control. When the small column window is selected no properties show for it in the Inspector window. Can anyone tell me how to use this control? I tried using the Boa Constructor help menu, and it led me to a very brief description of the list control, with no details on what it's properties were even.
