Simple stuff here... if I try to reference a cookie in Django via request.COOKIE["key"] if the cookie doesn't exist that will throw a key error. For Django's GET and POST, since they are QueryDict objects, I can just do if "foo" in request.GET which is wonderfully sophisticated... what's the closest thing to this for cookies tha...
What's the best way to make psycopg2 pass parameterized queries to PostgreSQL? I don't want to write my own escpaing mechanisms or adapters and the psycopg2 source code and examples are difficult to read in a web browser. If I need to switch to something like PyGreSQL or another python pg adapter, that's fine with me. I just want simple...
Let's focus on using SAP as the database engine and just doing different queries. Can I do it in Python? ...
Hello. I'm trying to implement row-based security checks for Django models. The idea is that when I access model manager I specify some additional info which is used in database queries so that only allowed instances are fetched from database. For example, we can have two models: Users and, say, Items. Each Item belongs to some User an...

So I wrote a Python program to handle a little data processing task. Here's a very brief specification in a made-up language of the computation I want: parse "%s %lf %s" aa bb cc | group_by aa | quickselect --key=bb 0:5 | \ flatten | format "%s %lf %s" aa bb cc That is, for each line, parse out a word, a floating-point number, an...
So I'm trying to comprehend the source file for csv2rec in matplotlib.mlab. It is used to take a csv file and parse the data into certain formats. So it may take a string '234' and convert it to int. or take a date string and make it into python datetimes. def get_converters(reader): converters = None for i, row in enumera...
I'm trying to create an array of all .asm files I need to build except for one that is causing me trouble right now. Here's what I have, based on the Scons "Handling Common Cases" page: projfiles['buildasm'] = ['#build/'+os.path.splitext(x)[0]+'.asm' for x in projfiles['a']]; (this maps paths of the form 'foo.a' to '#build/foo.asm'...
I'm new to both python and the python win32 extensions available at http://python.net/crew/skippy/win32/ but I can't find any documentation online or in the installation directories concerning what exactly the win32 extensions provide. Where is this information? ...
I am trying to access the Physical Memory of a Windows 2000 system (trying to do this without a memory dumping tool). My understanding is that I need to do this using the CreateFile function to create a handle. I have used an older version of win32dd to help me through this. Other documentation on the web points me to using either "\D...
I am looking for a help viewer like Windows CHM that basically provides support for adding content in HTML format define Table of Contents decent search It should work on Windows, Mac and Linux. Bonus points for also having support for generating a "plain HTML/javascript" version that can be viewed in any browser (albeit without sea...
I've been using zc.buildout more and more and I'm encountering problems with some recipes that I have solutions to. These packages generally fall into several categories: Package with no obvious links to a project site Package with links to free hosted service like github or google code Setup #2 is better then #1, but not much bett...
This seems like it should be easy, but I can't find the answer anywhere - nor able to derive one myself. How do you turn an unquoted python function/lambda into an AST? Here is what I'd like to be able to do. import ast class Walker(ast.NodeVisitor): pass # ... # note, this doesnt work as ast.parse wants a string tree = ast...
I was wondering what good networking libraries/frameworks there are for Python. Please provide a link to the standard API documentation for the library, and perhaps a link to a decent tutorial to get started with it. A comment or two about its advantages/disadvantages would be nice as well. ...
I'm looking for a very simple canvas for python. What I really need is the ability to draw lines and circles, move them around / get rid of them, and scroll the canvas (so, I'm ideally drawing on an infinite canvas, and just scrolling it around). Ideally, the code would look like: c = Canvas() l1 = c.line((x0, y0), (x1, y1)) l2 = c.line...
I'm using the example in python's 2.6 docs to begin a foray into embedding some python in C. The example C-code does not allow me to execute the following 1 line script: import math Using line: ./tmp.exe tmp foo bar it complains Traceback (most recent call last): File "/home/rbroger1/scripts/tmp.py", line 1, in <module> i...
As an exercise I'm writing a program to calculate the odds of rolling 5 die with the same number. The idea is to get the result via simulation as opposed to simple math though. My program is this: # rollFive.py from random import * def main(): n = input("Please enter the number of sims to run: ") hits = simNRolls(n) hits...
