Handling Vector/Array Data in Forms

I am using Django for a scientific applicaition. If I have to
transport a vector/array 'to' a form, dismantle it and display the
relevant information, it is easy. But how I capture vectors/array
datatypes 'from' the HTML forms (submitted by the user) in the
view.class and work with them.

i.e., i am asking if there is a efficient way of handling 'array' data
types in forms (other than using a single variable name in the (html)
form and doing a get_all from the (parent) request object)

Thanks!
