by Tamer Higazi June 2, 2013

June 2, 2013

Hi people! I have a problem passing an xs:anyType Parameter in "suds". The original sample is an application, where a "PHP Array" is being passed for the remoted method. What is the same type in python to accomplish the task?! doc with sample: http://kasapi.kasserver.com/dokumentation/?open=soap here the sample code with it's output: from suds.client import Client class KasAPI(object): def __init__(self): self.__WSDL = 'https://kasserver.com/schnittstelle/soap/wsdl/KasAuth.wsdl' self.client = Client(self.__WSDL) KasOBJ = KasAPI() print KasOBJ.client output: Suds ( https://fedorahosted.org/suds/ ) version: 0.4 GA build: R699-20100913 Service ( KasApiAuthenticationService ) tns="https://kasserver.com/" Prefixes (0) Ports (1): (KasApiAuthenticationPort) Methods (1): KasAuth(xs:anyType Params, ) Types (0):

Need to modify a Python Gui
by matt.doolittle33＠gmail.com June 2, 2013

June 2, 2013

Hi everybody, I have a Python GUI that displays some data in labeled fields. As new data comes in the fields clear and the old data is lost. I need to make a text box in the GUI that will display the cleared data in a scrolling list. I also need this scrolling list to be logged to a file in comma-seperated values for analysis at a later time. The fields I need to scroll and log are labeled in the “class TrafficPane(wx.Panel):” starting at line 64.

Mouse. I didn't mean "trackpoints" or similar devices, but full keyboard "navigation" of the entire GUI through shortcuts etc. A "touch-type" GUI is a "must have" for any application that's supposed to be used productively. The mouse is nice to "explore" a GUI or for occasional/leisurely use, but once you use an application daily to earn your living, it's a hopeless roadblock for productivity. As is the "response time" behaviour of "web applications". Besides that pathological non-operating system MS (Not Responding), btw. "No cursor animation ever" is an absolute "must have" requirement for productivity applications. > THIS is a professional programmer's workspace. :) And by "screenworkers" I didn't refer to programmers. Those people rarely have to use the stuff that they implement. Sincerely, Wolfgang

problem loading Python PIL module
by Elliot Perlman June 1, 2013

June 1, 2013

Hi, I have a Python program which worked successfully on several PCs using version 2.2 and showed videos using the PIL module version 1.1.5 . (All the rest works but the videos.) When I try to install the downloaded PIL module on my current laptop PC, I get the error message "Could not create key". I now have an Acer, Windows 7, 64-bit with Norton security. I tried turning off the firewall, but this did not help. Can anyone help me out? Thanks! Elliot Perlman

Cutting a deck of cards
by RVic June 1, 2013

June 1, 2013

Suppose I have a deck of cards, and I shuffle them import random cards = [] decks = 6 cards = list(range(13 * 4 * decks)) random.shuffle(cards) So now I have an array of cards. I would like to cut these cards at some random point (between 1 and 13 * 4 * decks - 1, moving the lower half of that to the top half of the cards array. For some reason, I can't see how this can be done (I know that it must be a simple line or two in Python, but I am really stuck here). Anyone have any direction they can give me on this? Thanks, RVic, python newbie

Python toplevel in a Web page
by Franck Ditter June 1, 2013

June 1, 2013

Hello, I wonder if I can find some source code example of a Python 3 toplevel box in a Web page. Something simple, no mySQL, no Django hammer, etc. Just the basics of the technology to get the content of a small text editor in which the user writes some Python script, to be analyzed (eval'ed) then whose result is to be written in another text box. Simple, pythonistic. Thanks for the pointer, franck
