x*x if x>10

[ssecorp]

I have seen somewhere that you can write something like:

x*x if x>10

but exactly that doesn't work and I can't get any variation to work.

it is possible to nest with an else too.
how do you write it?
and also, is it idiomatic? doesn't seem to add functionality, just
another way of doing the same thing which is quite unpythonic but I
remember reading it was added because it helped simplify the
expression of a certain type of operation.

It's a ternary operator as found in e.g. C or Java like this;
foo = <condition? <true-value: <false-value>;

And it's become available in python2.5, anything below that version will
throw an error.

It's called a ternary operator. The format is:

<label= <true-valueif <conditionelse <false-value>

it is possible to nest with an else too.

Sure. You can extend the <false-valuewith another ternary operator:

<label= <value1if <condition1else <value2if <condition2else
<value3>
