Actually, lambda forms are quite precisely documented at
http://docs.python.org/ref/lambdas.html if you feel than reading
the tutorial (specifically http://docs.python.org/tut/node6.html
section 4.7.5) is too base for you.

The official documentation can't list every possible permutation of the
various syntactic constructs. It does explain parenth

Wow, signs of developing inter-personal skills. I must assume that
c.l.py is having its benign influence on you too!

Thanks. That's what i was looking for.
where in Pytho doc can one find this? or the lambda with multiple
params?
Most often the lambda is not used directly, but passed to a function.
That is because the IT morons has been throughly brain

OK, I'll bite.
As with any other callable, you can simply call it like this:
a = 4
b = 24
(lambda x, y: x+y)(a, b)
Of course, you
once i have a expresson of a function, how to apply it to arguments?
e.g. if i have
lambda x,y:x+y
i have to applied it to a,b in my code.

Actually, Python's docs are centred around the fact that they expect people to

Since assignment is a statement in Python, not an expression,
and since "def f" is an assignment that binds a function
object to the na

Looking for lambda?

Not exactly sure what you're looking for but you can do the following:
def dosomething(numlist):
return numlist[0] + numlist[1]
numlist = [ 5, 10]
val = dosomething(numlist)
If so, that would be somewhat pointless. It's always best to keep it
simple. It looks like the function you wrote above
is there a way to write a expression of a function with more than 1
argument?
e.g., i want a expression that's equivalent to
def f(x,y)
return x+y
