I've been taking a brief look at Python.

Well I've set myself a task.
I have a text file containing a list of stock items
each line contains the number in stock followed by a tab followed by the
name of the item. I need to implement something that reads in the text
file and outputs the stock list in ascending or descending order of
quantity.
Nice problem. Easy but non-trivial.
Please note I am NOT asking for solutions.
Ok. With some inefficient redundancy, I believe it could be done in one
line in Python. Better code would take a few more.
In bash this is laughably trivial
sort -nr $1 | head -${2:-10}
Won't sort work alphabetically and leave the following as is?
1\talpha
11\tbeta
2\tgamma
The commandline options are "-nr". "n" means compare numerically and
"r" means reverse order.
