ProgrammingThis forum is for all programming questions.
The question does not have to be directly related to Linux and any language is fair game.

Introduction to Linux - A Hands on Guide
This guide was created as an overview of the Linux Operating System, geared toward new users as an exploration tour and getting started guide, with exercises at the end of each chapter.
For more advanced trainees it can be a desktop reference, and a collection of the base knowledge needed to proceed with system and network administration. This book contains many real life examples derived from the author's experience as a Linux system and network administrator, trainer and consultant. They hope these examples will help you to get a better understanding of the Linux system and that you feel encouraged to try out things on your own.

I am a green noob to python, and it looks like I cannot find a solution myself
I have a two-dimensional array like this (sorry but for some reason I cannot not produce square brackets in firefox to describe the arrays correctly - but that's an other issue):
dist(0)(0) = 25
dist(0)(1) = 1
dist(1)(0) = 12
dist(1)(1) = 2
dist(2)(0) = 11
dist(2)(1) = 3
Basically, column0 of the array contains values, column1 contains indexes.
What I want to do is to sort the above array on the values (column0), and then keep only the first (say) two rows, like this:
Traceback (most recent call last):
File "im.py", line 37, in ?
dist.sort(key=lambda a: a)
With the operator.itemgetter(0) thingy, strings like "array(0)(0) array(0)(1) ..." seem to replace the original elements of the array, and that's not the right behaviour, either
Here are the modules the script imports:
from Numeric import *
Should it import something more for the lambda thingy to work?
In the meantime I inserted the good old sorting algorithm into the python script, but that works badly slowly with the array (in real life the array has 80 rows and 2 colums, and there are 180 such arrays to sort)...
