I'm writing a script in Python that will monitor Twitter traffic over a long spell of time and I was wondering how I cou...
Here's an example of what I mean: class MyDecorator(object): def __call__(self, func): # At which point would I be able to access the decorated method's parent class's instance? # In the below example, I would want to access from here: myinstance def wrapper(*args, **kwargs): return func(*args...
I am using the Python Imaging Library to colorize a black and white image with a lookup table that defines the color relationships. The lookup table is simply a 256-element list of RGB tuples: >>> len(colors) 256 >>> colors[0] (255, 237, 237) >>> colors[127] (50, 196, 33) >>> My first version used the getpixel() and putpixel() met...
Using scipy's interpolate.splprep function get a parametric spline on parameter u, but the domain of u is not the line integral of the spline, it is a piecewise linear connection of the input coordinates. I've tried integrate.splint, but that just gives the individual integrals over u. Obviously, I can numerically integrate a bunch of ...

One of the arguments I make to my (Microbiology and Genetics) students is that "data" is/are messy, and Python can help with that (of course other languages can too). So here is a practical kind of web-based data-gathering exercise. I notice that there a few people who answer Python-related questions among the users with the highest re...

What is the most pythonic way to read in a named file, strip lines that are either empty, contain only spaces, or have # as a first character, and then process remaining lines? Assume it all fits easily in memory. Note: it's not tough to do this -- what I'm asking is for the most pythonic way. I've been writing a lot of Ruby and Java ...
