Like this?
a(*[1,2,3])

* is used in argument list to unpack array contents to arguments (like
here) or to pack arguments into an array,like in "def mymethod(*args)"

Excellent. Thanks a lot.

but what if i need e.g. to multiply all the array elements? you can't use * as a method.

If you just need to apply a function to each element of an array, take a look at the `map` method (if you need an array returned) or the `reduce` method (if you need a single element).
