passing variable arguments to a function

[Ryan Wilcox]

Hello all,

I want to be able to pass a variable number of parameters into a Python
function. Now, I know how to _receive_ variable arguments, but I don't
know how to _send_ them.

def myFunction(*arg s):
print args

myList = [1, 2, 3, 4]
myFunction(myLi st)

this function will print out ([1, 2, 3, 4]).

Except that's not what I want. I want the equivalent to:

myFunction(1, 2, 3, 4)

So, given an array, how can I unpack the array and pass all of the
elements into a Python function as parameters?

Thanks in advance!,
_Ryan Wilcox

myFunction(*myL ist)

same syntax:

myFunction(*myL ist)
