So student uses a FK for school. It shou... |
CherryPy deliberately doesn't require you to subclass from a framework-provided base class so that you are free to design your own inheritance mechanism, or, more importantly, use none at all. You are certainly free to define your own base class and inherit from it; in this way, you can standardize handler construction... |

I am trying to follow an example from an online tutorial regarding basic client-server socket programming using standard Python libraries (version 2.7), but I cannot get the example to work under Windows (Vista). It works fine in Ubuntu 11.10, so I know that the following code at least works in a UNIX-based environment... |

I'm trying to understand the numpy fft function, because my data reduction is acting weirdly. But now that I've transformed a simple sum of two sines, I get weird results. The peaks I have is extremely high and several points wide around zero, flattening the rest. Does anybody have a clue of what I might be doing wrong... |
Another thing that makes using Python pleasing is decorators. A decorator is a wrapper for a function (or method) that takes a function (or method) as an argument and returns a new function (or…) which is then bound to the name for the original function.
The newly-decorated function can then do things like checking the... |
ProDy works quite well, especially from within an existing Python script.
The following code takes an existing PDB file, performs some selection query on it, then saves it to another file.
import prody
def pdbsubset(inpdb, outpdb, selection):
with open(inpdb) as protf:
prot = prody.parsePDBStream(protf)

There's a program called granola which is theoretically used for energy saving. Instead of that, I use it for using the full speed of my CPU. To install it, if you're NOT using Quantal, just follow the instructions on the download page. Note it's freeware, to download it for free enter just $0 on the Custom Ammount tex... |

Kivy has a not-so-well known module, called recorder that allows to record and replay use... |

Writing this function in a more modern language like Java, C++ or C# isn't as odious, because automatic memory management takes care of the first half of this function. Writing the expression 'filter even [1..10]' in dynamic languages like Perl, Python and Rub... |
