I am using Python to parse entries from a log file, and display the entry contents using Tkinter and so far it's been excellent. The output is a grid of label widgets, but sometimes there are more rows than can be displayed on the screen. I'd like to add a scrollbar, which looks like it should be very easy, but I can't figure it out. Th...
Using Perforce, I'd like to be able to reject submits which contain files with Windows line endings (\r\n IIRC, maybe just \r anywhere as really we only want files with Unix line endings). Rather than dos2unix incoming files or similar, to help track down instances where users attempt to submit files with Windows line endings, I'd like ...
In python after imports, one can see the file, that has been loaded/where the module comes from. >>> import os >>> os.__file__ '/Users/tm/lib/python2.6/os.pyc' What would be the equivalent in ruby? >> require 'xmlrpc/client' => true >> ... ...
When I'm running Jinja2 in Google App Engine, I get useless debugging information. I gather this is because of this item in the FAQ: My tracebacks look weird. What’s happening? If the speedups module is not compiled and you are using a Python installation without ctypes (Python 2.4 without ctypes, Jython or Google’s AppEngine) J...

I was reading how Clojure is 'cool' because of its syntax + it runs on the JVM so it is multithreaded etc. etc. Are languages like ruby and python single threaded in nature then? (when running as a web app). What are the underlying differences between python/ruby and say java running on tomcat? Doesn't the web server have a pool of th...
The program I've written stores a large amount of data in dictionaries. Specifically, I'm creating 1588 instances of a class, each of which contains 15 dictionaries with 1500 float to float mappings. This process has been using up the 2GB of memory on my laptop pretty quickly (I start writing to swap at about the 1000th instance of the c...
It's been said in a couple places (here and here) that Python's emphasis on "it's easier to ask for forgiveness than permission" (EAFP) should be tempered with the idea that exceptions should only be called in truly exceptional cases. Consider the following, in which we're popping and pushing on a priority queue until only one element is...

I need to generate a multipart/mime message to send as a response to a HTTP request but am hitting either a bug or limitation in the Python email.* package. The problem is that using Python 2.6, the message.as_string() call below generates a string with \n rather that CRLF as the line endings: message = MIMEMultipart() for image in ima...

I'm using rpy2 to do data analysis and plotting in python. It works fine except for the fact that when I draw a plot, it's window hangs around until the program terminates. Is there a way to clear the plot during runtime? Additionally, If I ever resize the window, the plot disappears, but the window remains. When using R interactively, r...

Hey, I am a newcomer to the Python and Twisted game so excuse the ignorance I will likely be asking this question with. As a sort of first program, I am trying to write a basic HTTP server using twisted.web.sever which would simply print to screen the HTTP request, and then print to screen the HTTP response. I am trying to print the ent...
