This is a follow-up questions on a previous one. Consider this code, which is less toyish than the one in the previous question (but still much simpler than my real one) import sys data=[] for line in open(sys.argv[1]): data.append(line[-1]) print data[-1] Now, I was expecting a longer run time (my benchmark file is 65150224 li...
In Django, I have two models: class Product(models.Model): name = models.CharField(max_length = 50) categories = models.ManyToManyField(Category) class ProductRank(models.Model): product = models.ForeignKey(Product) rank = models.IntegerField(default = 0) I put the rank into a separate table because every view of a pa...
I'm wondering if it's possible to make a method which behaves differently when called as a class method than when called as an instance method. For example, as a skills-improvement project, I'm writing a Matrix class (yes, I know there are perfectly good matrix classes already out there). I've created a class method for it called identi...
While using regex to help solve a problem in the Python Challenge, I came across some behaviour that confused me. from here: (...) Matches whatever regular expression is inside the parentheses. and '+' Causes the resulting RE to match 1 or more repetitions of the preceding RE. So this makes sense: >>>import re >>>re.findall(r"(\d+...

In the many Python applications I've created, I often create simple modules containing nothing but constants to be used as config files. Additionally, because the config file is actually a Python code file, I can add simple logic for changing variables depending on a debug level, etc. While this works great for internal applications, I...
Hi! How do I get a tuple/list element given a condition in python? This occurs pretty often and I am looking for a nice-few-lines-pythonic way of doing this. here could be an example: Consider a tuple containing 2D points coordinates like this: points = [[x1, y1],[x2, y2],[x3, y3], ...] And I would like to get the point that minimi...
I need to download several files via http in Python. The most obvious way to do it is just using urllib2: import urllib2 u = urllib2.urlopen('http://server.com/file.html') localFile = open('file.html', 'w') localFile.write(u.read()) localFile.close() But I'll have to deal with the URLs that are nasty in some way, say like this: http:...

So, there seems to be a few questions asking about removing files/directories matching certain cases, but I'm looking for the exact opposite: Delete EVERYTHING in a folder that DOESN'T match my provided examples. For example, here is an example directory tree: . |-- coke | |-- diet | |-- regular | `-- vanilla |-- icecream | |-...
I am a python newbie trying to achieve the following: I have a list of lists: lst = [[567,345,234],[253,465,756, 2345],[333,777,111, 555]] I want map lst into another list containing only the second smallest number from each sublist. So the result should be: [345, 465, 333] For example if I were just interested in the smallest num...
Hi all, given a somewhat complex file of unknown specification that among other things contains an uncompressed bitmap file (.BMP), how would you extract it in Python? Scan for the "BM" tag and see if the following bytes "resemble" a BMP header? ...
Hi everybody! I have a method that creates a new node in a tree - either left or right. If the value is lower than my current value it is inserted on the left, otherwise on the right side. I want to refactor this code, so that I first see on which side I have to insert my element, and then insert it. Before I implemented this twice: On...
When debugging, I like to print out all the inputs and outputs of a function (I know I need a better IDE, but humour me, this could be used for error reporting). So, I'd ideally like to have: @debuggable def myfunc(argA,argB,argC): return argB+1 and use a global variable to switch on or off debugging. No, you don't like globals ei...
I'm developing using Django on Windows. I have a model with an imagefield, and use a form to fill it. Images get uploaded without problem. The problem occurs when I attempt to show an uploaded image inside a template by coding this: <img src ='{{object.image.url}}'/> (object is an instance of the relevant model, and image is the name ...
