Is this pylint error message valid or silly?

Here's the code that I'm feeding to pylint: $ cat f.py from datetime import datetime def f(c="today"): if c == "today": c = datetime.today() return c.date() And here's what pylint says: $ pylint -e f.py No config file found, using defau

itertools.intersect?

Hi, During a fun coding session yesterday, I came across a problem that I thought was already solved by itertools, but on investigation it seems it isn't. The problem is simple: given one or more ordered sequences, return only the objects that appear in each sequence, without reading the whole se

Where should I store docs in my project?

I used paster to create a project named pitz. I'm writing a bunch of user documentation. Where should I put it? The project looks a little like this: /home/matt/projects/pitz setup.py pitz/ __init__.py # has my project code docs/ # has my reST files

How to test python snippets in my documents?

I'm using a homemade script to verify some code samples in my documentation. Here it is: #! /usr/bin/env python2.6 # vim: set expandtab ts=4 sw=4 filetype=python: import doctest, os, sys def main(s): "Run doctest.testfile(s, None)" return doctest.testfile(s, No

How can I get access to the function called as a property?

I use a @property decorator to turn some methods on a class into properties. I want to be able to access some of the attributes of the original funtion, but I don't know how to get to it. Any ideas? Matt -- http://mail.python.org/mailman/listinfo/python-list

I'm working on a really simple workflow for my bug tracker. I want filed bugs to start in an UNSTARTED status. From there, they can go to STARTED. >From STARTED, bugs can go to FINISHED or ABANDONED. I know I can easily hard-code this stuff into some if-clauses, but I expect to need to add a lo

How should I use grep from python?

I'm writing a command-line application and I want to search through lots of text files for a string. Instead of writing the python code to do this, I want to use grep. This is the command I want to run: $ grep -l foo dir In other words, I want to list all files in the directory dir that contain

How to walk up parent directories?

Is there already a tool in the standard library to let me walk up from a subdirectory to the top of my file system? In other words, I'm looking for something like: >>> for x in walkup('/home/matt/projects'): ... print(x) /home/matt/projects /home/matt /home / I know I
