There is no such special method __raise__ (at least none that I have ever heard of or that I can that Python supports it?

Say I have the following code.
def foo(): foobar = None if foobar is not None: raise foobar
When I run this code through pylint, I get the following error:
E0702:4:foo: Raising NoneType while only classes, instances or string are allowed

The only time I know that you have to manually raise.
The more normal way to end the iteration a StopIteration to be raised on your behalf.
It doesn't have to, but it can raise a StopIteration .

If there is no user with an id of 1 in the database, trying User.find(1) will raise an exception.
Why is this?

If no record can be found for all of the listed ids... .
Because that's the way the architects intended find(id) to work, as indicated in the RDoc:
Find by id - This can either be a specific id (1), a list of ids (1, 5, 6), or an array of ids ([5, 6, 10]) .

It's pow or powf in <math.h>
There is no special infix operator like in Visual Basic or Python
pow(2.0,1.0) pow(2.0,... .
Pow
Use the pow(x,y) function: See Here
Just include math.h and you're all set .
More info here.
Pow() in the cmath library.
