Yes is very possible to do this with python.
Checkout the os.system and os.popen functions to run external commands
(chmod, chown).
Reading the list of users and groups should be easy, just open the
file and read line by line and parse, you can do it as simple as
splitting the line on colon chara

Although I should have expected at least a few problems, I have a question
about a glitch in vista using a wx-implemented script.
Here's the example script-

This will always be true, you multiply by two then check if the result
is divisible by two.

Correct, they only work on the current environment.

I came across the topic of internal Python IDs recently, and learned that the
internal numeric ids of small integers are cached to increase speed. I had read
that as of 2.5, this applied to integers between -1 and 100. However, doing
some quick tests, this seems not to be accurate:

Imagine you are in a DOS command session

Dear list,
I have been teaching Python with minimal knowledege myself!! I need to be able
to search a text file that perhaps contains names and scores. How do I find a
particular name, change the score and then save the changes back to the text
file again??
Thanks for any help. Diana

I notice this is homework so I won't give a direct answer.
But look at the mod operator '%' - It returns the remainder
of an integer division. An even number is exactly divisible
