I've done a lot of searching to try to find a way to print PIL images to a normal (i.e. non-PostScript) printer through Python on a Windows system... and have found squat! The only sample I found used a hokey hook through PythonWin via a shellExecute command. Does ANYONE have Python code to print PIL images? Thanks!

Hi All, I've got a problem I'm seeing when trying to use the struct module to send data to a different machine. Actually I'm making a condensed file that gets transferred to and read on a BREW enabled cell-phone, essentially I'm trying to format content as if it were being streamed over a socket. So I am trying to write a string by...

I wonder if there is any difference in using if/else and try/except when checking some return values in functions. For example: def getValue(self): try: return self.values except KeyError: return None

Is there a better way to append certain chars in a string with a backslash that the example below? chr = "#$%^&_{}" # special chars to look out for str = "123 45^ & 00 0_" # string to convert n = "" # init new string for i in str: if i in chr: # if special character in str n+='\\' # append...

I've been using RRDtool/Python/Apache with great success on Linux but now I need to implement on Windoze2K and I don't have a Windoze C compiler. Is there a RRDtool binary and Python module for it which I can just plug in? TIA

Hi all. I'm learning Python, and get stuck once in a while. I've come up with an idea. I'd like to start an online Python Study Group with others trying to learn Python as well. I emailed my ideas to someone else in the same boat, so I'm just going to past that here. +++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ I'm realy...

Hi group! I need to extract some text (well numbers actually) from a bunch of similarly looking .png images. After extraction the numbers will be fed to a Python script for further processing. Any good ideas on how to go about with this? I have no idea whatsoever about how to extract the numbers out of the images... Thanks in advance,

The docs for 2.2 and 2.3 contain a "What's new" section. Are there any such sections for 2.0 and 2.1? If so, where are they? Thanks. Edward -------------------------------------------------------------------- Edward K. Ream email: edreamleo@charter.net Leo: Literate Editor with Outlines

Dear list, I'm trying to install python2.3.1 on an SCO-box. After running ./configure --prefix=/usrdir/rogere the output of make shows (among others:) running build running build_ext building 'struct' extension creating build

When I am typing in code in IDLE, these little context sensitive helps keep popping up right next to the mouse cursor. Is there any way to turn this feature off? Thanks! -- Audio Bible Online: http://www.audio-bible.com/

This is probably an easy question, but I can't find a function (maybe my syntax is off...) to search for in a string. If someone would help out, I'd appreciate it! Also, how would you recommend searching for the following in the same string: -

Now that Thomas is back from vacation ;-) I cannot get the example service to work using Python 2.3 and the latest released py2exe (or the cvs version) on Win2k SP3. I can run the sample service .py file ok, but once it's inside a py2exe generated exe.. no working. The error in the event log is: The description for Event ID ( 240 ) in...

I am really stuck here. I would love to use an IDE to debug my programs, but they are all set to accept input from stdin, ie python rdip.py < scriptfile.txt I can't figure out how to do this in PythonWin, IDLE, or Komodo. Help! I've been poring through manuals and google for hours trying to figure this out.

Hi, After upgrading my Python interpreter to 2.3.1 I constantly get warnings like this: DeprecationWarning: Non-ASCII character '\xe6' in file mumble.py on line 2, but no encoding declared; see http://www.python.org/peps/pep-0263.html for details And while I understand the problem, I cannot fathom why Python

I've spent last hour trying to debug my code, when I found out that instead of executing object's method I accidentaly overridden it with variable (see below example). My stupid! But as the system becomes more complex, I begun to wonder how to avoid such situations in the future. Does anybody have some experiences about that? Simple...

Hi all I tried to install the mod_python (www.modpython.org) for Apache Webserver. By configure with ../configure --with-apxs /usr/sbin/apxs2-prefork i get this error: configure: error: yes not found or not executable SuSE Linux 8.2

Hi. I have a "style" question: Sometimes, modules will only be used in a particular, optional, part of a program (function, class), that will not always be used when the application is run. So I think it is better to import them only there, not on the top of the file (together with the other imports). Is that okay, or are there good reasons...

I am creating a dialog in wxPython for log in purposes. Basically when the user clicks the ok button, the dialog box saves the user name and password as class attributes. Then as long as the dialog exists calling MyDialog.GetUserName() and MyDialog.GetPassword() returns them. This seems insecure to me. Is there a better way to go about this...

Hello, Hopefully someone can help me out with this issue... I have a python script that needs to run a shell command and be able to react to output from that command as it occurs (as opposed to waiting for the whole command to complete and then parsing the output). Is this possible with Python? I created a test script that prints a...

I am trying to figure out how a complex program written in python works. I am new to python so looking at the source code directly is not helping me much. As such, I am running the program under IDLE so I can step through the code. The program runs fine when it is run by itself. However, when I try to run the program in IDLE, I run into...

.. . . Most people I know who use Java only do so because they're forced to by the company they work for. They never say they "enjoy" the language, as compared to those associates who, for example, use Python and say that they'd rather code in Python than be given their choice of supermodel sex slave. .. . .

While trying to print a none empty list, I accidentaly put an "else" statement with a "for" instead of "if". Here is what I had: if ( len(mylist)> 0) : for x,y in mylist: print x,y else: print "Empty list" which was supposed to be:

Hi, I have a couple of general requests for pointers to python examples and design advice. I'm looking for examples of MVC-based GUI controls done in python (model-view-controller). Also, examples where something like a simulation model running in its own thread sends fast updates to a GUI in near real-time. The only examples I've seen,...
