Hello Steve,
I was wondering if you had working examples of your automated tasks in python
... I am asking because I am starting out in Python, and I believe I can save
my company time and headaches by automating a lot of the tasks we have.
I would like to study your code and see if I can use it

Hi all
This is what I want to do: On a LAMP server, people are able
to request for an instance of a particular LAMP application
by submitting a few options. That involves creating a couple
of directories, getting the code, writing a config file,
setting file permissions and creating a mysql user.

Is there a unique method in python to unique a list? thanks
--
http://mail.python.org/mailman/listinfo/python-list
If you don't need to retain order you can just use a set,
set([1, 1, 2, 3, 4]) = set([1, 2, 3, 4])
But set's don't retain order.

I don't believe there's a method for that, but if you don't care about
order, try turning your list into a set and then back into a list.

Many thanks.
I put all the set result into a list first . Then it will work and work

Thanks first, I could understand the second approach easily. The first
approach is a bit puzzling. Why are seen=set() and seen.add(x) still
necessary there if we can use unique.append(x) alone? Thanks for your
enlightenment.

Try backdenting that statement. You're currently doing it at every
iteration of the loop - that's why it's so much slower.
But you'll probably find it b
For a short list the difference is going to be negligible.
For a long list the difference is that checking if an item in a list requires
iterating over the list internally to find it but checking if an item is inside
of a set uses a faster method that doesn't require iterating over the list.
