Re: the scaling of pics in pygame
Isn't PIL best suited for things like this? The resize function should do what you're looking for: http://www.pythonware.com/library/pil/handbook/image.htm On Wed, Apr 2, 2008 at 6:59 AM, [EMAIL PROTECTED] wrote: On Apr 1, 9:44 pm, Jimmy [EMAIL PROTECTED] wrote: Hi, everyone I am using Pygame to write a small program.

Re: convert pdf to png

Carl K -- http://mail.python.org/mailman/listinfo/python-list PIL's support for pdf files is write only, so thats out of the question. I just tried ImageMagik from the console and it converted a pdf into png in a snap, so that seems to be your best bet. -- nasser -- http://mail.python.org/mailman/listinfo/python-list
Re: How to generate pdf file from an html page??

An HTML to PDF converter is no trivial task. You would essentially have to implement an HTML layout engine that outputs PDF files. Not only does that mean you would have to programatically produce a PDF file, but it means you would have to parse and correctly render HTML and CSS according to accepted web standards, the W3C's specifications. This has proved difficult to do and get right in practice, as is evident from the browser compatibility issues that continue to plague the web. Theres a package called Prince that's supposed to do an excellent job. Check it out: http://www.princexml.com/ Its layout engine surpasses some browsers in terms of compatibility with web standards. I don't think its free for commercial use, though, so this might depend on what exactly you're trying to do. An alternative idea it to wait for Firefox 3 to come out. If I'm not mistaken, it will feature a new version of the Gecko layout engine which will use Cairo for all its rendering. Coincidently, Cairo can be made to output PDF files. So, you may be able to hack something together. -- nasser -- http://mail.python.org/mailman/listinfo/python-list
Re: Get()
The grid method of these widgets returns None. When you say something like: ent = Entry(root, fg = '#3a3a3a', bg = 'white', relief = 'groove').grid(row = 0, padx = 3, pady = 3) You're actually assigning the value of the last method on the right hand side (in this case, grid) to the variable on the left hand side (in this case ent). Since grid returns None, ent is set to None, and the insert function fails. What you want to do is replace your GUI initialization code with something like this: ent = Entry(root, fg = '#3a3a3a', bg = 'white', relief = 'groove') ent.grid(row = 0, padx = 3, pady = 3) button = Button(root, text = Remember, command = insert, relief = 'groove', fg = '#3a3a3a') button.grid(row = 0, column = 1, padx = 3, pady = 3) box = Listbox(root, bg = '#ebe9ed', relief = 'groove') box.grid(row = 2, columnspan = 2, sticky = W+E, padx = 3) This way ent, button and box get set to their respective widgets, the grid method does its thing and the insert function works as expected. -- nasser -- http://mail.python.org/mailman/listinfo/python-list
Re: Any way to program custom syntax to python prompt? I want to edit matrices.

The ; sign is reserved, the [ ] is used for lists. I think mosi was looking to dynamically modify the syntax of Python itself, as opposed to working around the existing syntax. This includes things like messing with reserved symbols and keywords. The interpreter is compiled with these definitions built in, so to change them would conceivably require a recompile. If this is the case, then mosi may be out of luck. Then again, people have done some interesting dynamic modifications to the interpreter during runtime without recompiling. Psyco is the best example of this that comes to mind. Maybe someone more versed in Psyco-esque interpreter voodoo would be able to help. -- nasser -- http://mail.python.org/mailman/listinfo/python-list
Re: project - trivia game
Shawn, First of all, next time try and isolate the problem yourself and send a short snippet of code demonstrating the behavior you're having trouble with. This makes it easier for other people to understand what is going on and help you in a more focused way. On Dec 5, 2007 2:43 AM, Shawn Minisall [EMAIL PROTECTED] wrote: For my final project, I'm trying to do a GUI based game similar to are which GUI toolkit are you using? you smarter then a 5th grader. I've been working on it and am stuck with some code someone helped me with to randomize the A,B,C,D letters that the correct answer is assigned too. The code that does this is highlighted in bold and the code that assigns it to a variable is also in bold so I can test it in the console window. Problem is, it's always stuck at letter A and doesn't always give the correct answer. The correct answer is always position 1 in my make math question list. Could someone please help? Your randomization code works. There are two issues that are causing your problem, though. 1. You provide no mechanism to keep track of what answers are correct. In the whole program, there is no notion of whether an answer is right or wrong. So you can't expect to get the correct answer to a question without telling the machine which one it is. Although it may start out at position 1, this is lost after randomization. 2. Your program is hardcoded to always pick letter A pResult = (currentScreen[0].getText()) print pResult cResult = (currentScreen[2].getText()) print cResult Following the definition of drawQuestion, currentScreen[0] will contain entchoice which has text 'A', and currentScreen[2] will always contain answer A and the first answer in the list, regardless of whether or not it is correct (again, the machine has no way of knowing). I'm not completely sure what you're trying to do here (pResult, cResult...problemResult, correctResult?), so some more explanation would help. Also, some general comments: #Picks random question qNum = randrange(0, len(currentList)) qList = currentList[qNum] can be replaced with qList = choice(currentList) (you would have to replace currentList.pop(qNum) with currentList.remove(qList) ) aList = [] tmpList = qList[1:5] #Randomizes answers while(len(tmpList) 0): rNum = randrange(0, len(tmpList)) aList.append(tmpList[rNum]) tmpList.pop(rNum) can be replaced with aList = qList[1:5] shuffle(aList) thanks BTW, to whoever asked me why I don't use functions b4, I'm using them now that I've learned how to... :P ;) Probably a good idea :) Good luck with everything -- nasser -- http://mail.python.org/mailman/listinfo/python-list
