In my example code below, is the counter = 0 really required, or is there a better, more Python, way to get access to a loop counter? I saw a few PEPs related to loop counters, but they were either deferred or rejected (PEP 212 and PEP 281). This is a simplified example of my problem. In my real application this is done with graphics an...

How would you create an algorithm to solve the following puzzle, "Mastermind"? Your opponent has chosen four different colours from a set of six (yellow, blue, green, red, orange, purple). You must guess which they have chosen, and in what order. After each guess, your opponent tells you how many (but not which) of the colours you guess...
Hello! Consider: pipe_read, pipe_write = os.pipe() Now, I would like to know two things: (1) I have two threads. If I guarantee that only one is reading os.read(pipe_read,n) and the other is only writing os.write(pipe_write), will I have any problem, even if the two threads do it simultaneously? Will I get all data that was written ...
I'm trying to slowly knock out all of the intricacies of python. Basically, I'm looking for some way, in python, to take a string of characters and push them all over by 'x' characters. For example, inputing abcdefg will give me cdefghi (if x is 2). Thanks! ...
Does anyone know how to associate the py extension with the python interpreter on Mac OS X 10.5.7? I have gotten as far as selecting the application with which to associate it (/System/Library/Frameworks/Python.framework/Versions/2.5/bin/python), but the python executable appears as a non-selectable grayed-out item. Any ideas? Thanks, -...
Hi, I wonder what is the best way to handle parallel SSH connections in python. I need to open several SSH connections to keep in background and to feed commands in interactive or timed batch way. Is this possible to do it with the paramiko libraries? It would be nice not to spawn a different SSH process for each connection. Thanks. ...
I'm trying to make a web app that will manage my Mercurial repositories for me. I want it so that when I tell it to load repository X: Connect to a MySQL server and make sure X exists. Check if the user is allowed to access the repository. If above is true, get the location of X from a mysql server. Run a hgweb cgi script (python) cont...
The Python manual says that you can create modules for Python in both C and C++. Can you take advantage of things like classes and templates when using C++? Wouldn't it create incompatibilities with the rest of the libraries and with the interpreter? ...
I'm looking for a way to read specific files from a rar archive into memory. Specifically they are a collection of numbered image files (I'm writing a comic reader). While I can simply unrar these files and load them as needed (deleting them when done), I'd prefer to avoid that if possible. That all said, I'd prefer a solution that's ...

How should new nodes be added with SQLAlchemy to a tree implemented using the Nested Set Model? class Category(Base): __tablename__ = 'categories' id = Column(Integer, primary_key=True) name = Column(String(128), nullable=False) lft = Column(Integer, nullable=False, unique=True) rgt = Column(Integer, nullable=False,...
I realize this is a dated question since appengine now comes in java, but I have a python appengine app that I want to access via GWT. Python is just better for server-side text processing (using pyparsing of course!). I have tried to interpret GWT's client-side RPC and that is convoluted since there is no python counterpart (python-gw...
This question is in relation to another question asked here: Sorting 1M records I have since figured out the problem I was having with sorting. I was sorting items from a dictionary into a list every time I updated the data. I have since realized that a lot of the power of Python's sort resides in the fact that it sorts data more quic...
