When I'm trying to create an extended user profile I'm getting UserProfile object is unsubscriptable. I've googled for solution, but 'your object is not a sequence' does not help here much. Here's the function I'm using, 'temp_data' is the data from my registration form : def create_user(request): data = request.session['temp_da...
I'm using MySQLdb and when I perform an UPDATE to a table row I sometimes get an infinite process hang. At first I thought, maybe its COMMIT since the table is Innodb, but even with autocommit(True) and db.commit() after each update I still get the hang. Is it possible there is a row lock and the query just fails to carry out? Is there...

How can I sort a list by a key described by an arbitrary function? For example, if I have: mylist = [["quux", 1, "a"], ["bar", 0, "b"]] I'd like to sort "mylist" by the second element of each member, e.g. sort(mylist, key=lambda x: x[1]) how can I do this? thanks. ...
I've seen various answers to the ball collision detection question explaining why sqrt operations are slow, why absolute value operations are fast on floating ponts etc. How can I find out which operations are expensive and which are not? Basically, I'm looking for a resource where I can learn about the implementation of all the python ...
I must be missing something in the code. I've rewritten an 'echo server' example to do a bit more when it receives something. This is how it currently looks: #!/usr/bin/env python import select import socket import sys import threading import time import Queue globuser = {} queue = Queue.Queue() class Server: def __init__(self)...
What is the standard way to enter degrees into python? My total station gives degrees in degree-minute-second format. I could write a function to convert this to a decimal degree but I would like to know if there is a common way to do this that I am unaware of. -Chris ...
Assuming that x is an integer, the construct if x: is functionally the same as if x != 0: in Python. Some languages' style guides explicitly forbid against the former -- for example, ActionScript/Flex's style guide states that you should never implicitly cast an int to bool for this sort of thing. Does Python have a preference? A link t...
From what little I know, + op for lists only requires the 2nd operand to be iterable, which "ha" clearly is. Thanks in advance. In Code: >>> x = [] >>> x += "ha" >>> x ['h', 'a'] >>> x = x + "ha" Traceback (most recent call last): File "<stdin>", line 1, in <module> TypeError: can only concatenate list (not "str") to list ...

I apologize if you know nothing about Python, however, the following snippet should be very readable to anyone. The only trick to watch out for - indexing a list with [-1] gives you the last element if there is one, or raises an exception. >>> fileName = 'TheFileName.Something.xMl' >>> fileNameList = fileName.split('.') >>> assert(len(f...
I've been exposed via StackOverflow to pHash, a C++ perceptual hash library for audio, video, images, and text fingerprinting - recently with preliminary bindings for PHP, C# and Java. I'm interested in studying these algorithms and I'm wondering if there are any open-source pure Python or PHP implementations of the same / similar algor...
