I'm writing a log collection / analysis application in Python and I need to write a "rules engine" to match and act on log messages.
It needs to feature:
Regular expression matching for the message itself
Arithmetic comparisons for message severity/priority
Boolean operators
I envision An example rule would probably be... |

This series of articles by David Mertz assumes readers have a familiarity with basic object-oriented programming concepts: inheritance, encapsulation, and polymorphism. We pick up where the basics leave off; how some "exotic" techniques can make applied programming tasks easier, more maintainable, and just plain more e... |

I have a string "42 0" (for example) and need to enter into an array the two integers. can i do a .split on a space?
thanks in advance
text = "42 0"
nums = [int(n) for n in text.split()]

>>> "42 0".s... |
You could split the problem up into two pieces:
Some kind of search algorithm that will enumerate possible strings in the grid.
A way of testing whether a string is a valid word.
Ideally, (2) should also include a way of testing whether a string is a prefix of a valid word â this will allow you to prune your search a... |
I need to read data from a huge table (>1million rows, 16 cols of raw text) and do some processing on it. Reading it row by row seems very slow (python, MySQLdb) indeed and I would like to be able to read multiple rows at a time (possibly parallelize it).
Just FYI, my code currently looks something like this:

First let your urls extend beyond images:

urls = (
'/images/(.*)', 'images' #this is where the image folder is located....
