A recent windows update delivered the Windows Power Shell to my

I'd heard of this but never used it till now. I've only started
playing with it but
it is essentially DOS on steroids. It brings Windows users a shell

to be very close to Unix shells like Bash in power and flex

You need to figure out how to get your email program to do quoting. As
it stands, there's no good way to tell what part of the following
message was from you, and what part was from wayne, or maybe others.
Probably all you need to do is to do a reply-all to the message, and

Hello,
I have to make a programm which can test if a number is a prime.
I know a prime is a number which can only be diveded by 1 and itself.
One way is was thinking about is to make a loop which try if % has output 0.
But that don't work.
Can someone give me a hint what's the best
For this problem u will get lots of solutions on the net.
e.g wilson's theorem , sieve of eranthoses etc.

Googling 'computing prime numbers' produced about 64,100,000 results . That
should certainly get you started.

You can use raw_input like for e.g.
u_input = raw_input("user_command")
n then u can check u_input against anything. if doesn't matches then u can
throw an error.
I hope it shall help you.

And if you just search Google for "Python prime number algorithm"? Perhaps it's
cheating, so you'll have to try and fully understand the code first before you
run it (

Alan,
I have used WPS 1.0 for some time at work to script software installs, etc.
It is very powerful and gives full .NET visibility to "DOS" level scripts.
In fact, it is a plausible replacement for VB for most administrative
scripting work in the Windows environment.
Some good resources:

If your while condition is True, you get into the loop.
Inside the loop, however, you never change anything t

The very best first feature to learn is the "foreach" command. It elegantly
solves the icky, age old, problem in DOS batch of reading in a list of
values from a file and doing something with them. This alone sold me
completely on WPS.
For instance, here is and actual script I used to push an in

Or more specifically, it must be indented further than the while
