• How do I randomly select from a list in Python?

  - by Liam Block

  Basically, I've got a homework task of programming a text based battle simulator in Python. Obviously I've gone with pokémon... I would like the enemy to be randomly selected, however I don't know how to randomly select from a list... foo = ['a', 'b', 'c', 'd', 'e'] from random import choice print choice(foo) This is what I've been told to try but I've got no modules or anything imported... How can I make this work, appreciated.

Also, being able to drag and select multiple cells. Then send all of this via $_POST to another php script. Problem is, I have no idea where to start. Any suggestions?

• Need a fast programming language that can drive two printers

  - by Pete

  I have a rather unusual application that isn't working the way I need, and I hope someone here will have some suggestions or at least a direction to investigate. We have a museum exhibit that has a computer at the entrance driving two small receipt printers. There are two buttons on a console, wired to the left and right buttons of a disemboweled mouse. The two printers and associated buttons are for girls and boys, each button does a random selection from a database of names and prints a small ticket on the appropriate printer with a graphic image, a few words about the exhibit and the randomly chosen name. Conceptually all is well, but it hangs quite often. I got the project at the last minute, because the original designer got bogged down and couldn't deliver, so the exhibit's author asked me the day before opening, whether I could write something that would work. I did it in Word, since I am an experienced VBA programmer. Several other avenues I attempted first all lead to dead ends - one couldn't do graphics, another couldn't handle two printers, yet another couldn't change fonts and so on. The problem is that it simply isn't fast enough - Word can only drive one printer at a time and changing the active printer takes a long time. Not by office standards, where a second or two of delay before a printer starts working on your document is not an issue, but here I need more or less instant response. If kids press a button and nothing happens, they press it over and over until something does happen, resulting in maybe half a dozen commands being sent before the printer starts reacting. Sometimes it jams the program completely, since boys and girls will be pressing the two buttons simultaneously and Word locks up, and even when it doesn't jam, the printers then spit out a stream of tickets, making a mess. The kids start squabbling over which ticket is whose, pulling them out of the printers, snarling the paper tape, jamming the printer and generally making a mess of the whole affair, often necessitating the exhibit caretakers having to restart the computer and clear torn bits of paper out the printers. What I need is some sort of fast programming language that can drive two printers *-simultaneously-*, not the MSOffice claptrap of having to switch the active printer, that can react to both left and right mouse button click events, can print a small graphic image and can print in different font sizes and styles and. I don't need many, but it's not all in one typeface. Can anyone suggest what I might use for this? I don't even know if it's possible at all under Windows, whether the "single active printer" garbage is an Office artifact, or a Windows restriction. My little Commodore-64 twenty-five years ago had two printers attached to it and drove both simultaneously with no difficulties - it doesn't seem to me it should be such an impossible requirement today.

• List DOM Documents attributes and methods using Javascript

  Just wondering if it's possible to print and list all methods and attributes available to the DOM document itself using Javascript? So I would get something like so: Document.doctype Document.implementation Document.documentElement Document.createElement Document.createDocumentFragment Document.createTextNode Document.createComment Document.createProcessingInstruction etc... etc...

• What is the process of turning HTML into Postscript programmatically

  - by Dean

  I am trying to understand what the process is of turning HTML into a PDF/Postscript programmatically All Google searches turn up libraries to do this, but I am more interested in the actual process required. I know you could just set up a Postscript printer and print directly to that, but some of these libraries appear to create the PDF on the fly to allow previews etc. has anyone had any experience in this, or can provide any guidance?

• Sequential numbering from recursive function? e.g. 2, 2.1, 2.1.1, 2.2, 2.2.1

  - by Pete

  I have a recursive function reading a "table of contents" of documents from a database. I would like to print numbering with the document that reflects where the item is in the tree, e.g. First item, 1.1 Child of first item, 1.1.1 Child of child of first item, 1.2 Child of first item, Second item, 2.1 Child of second item, etc. Rather stumped about this at the moment - help please?

• create a dict of lists from a string

  - by Chris Card

  I want to convert a string such as 'a=b,a=c,a=d,b=e' into a dict of lists {'a': ['b', 'c', 'd'], 'b': ['e']} in Python 2.6. My current solution is this: def merge(d1, d2): for k, v in d2.items(): if k in d1: if type(d1[k]) != type(list()): d1[k] = list(d1[k]) d1[k].append(v) else: d1[k] = list(v) return d1 record = 'a=b,a=c,a=d,b=e' print reduce(merge, map(dict,[[x.split('=')] for x in record.split(',')])) which I'm sure is unnecessarily complicated. Any better solutions?

Just an ability to build a query with user friendly interface, then show the result of this query in some table and maybe export it to Excel or print.

• tapestry5 page to render plain text

  - by pstanton

  Hi All, I've been looking but can't find the the documentation: Is there a way to have a page render a response without the wrapping HTML elements and just print whatever is provided in the body of the tml or alternatively whatever is set in MarkupWriter.write during @BeginRender? I need a page that does some server side processing and returns pure javascript for an external application to request. If that is impossible, is it possible to expose the tapestry Ioc to a servlet in the same app? Thanks, p.

• Xcode C++ debugging

  - by mousebird

  I'm looking for a way to have the Xcode IDE pick up on the contents of my weird Boost template classes. Basically, classes complex enough that Xcode can't display their contents correctly. Is there something like the Objective C -description method or toString() in Java that Xcode will look for? At the moment I'm just implementing print() methods and invoking them in gdb, but that's likely to confuse other developers.
