How can I verify that a passed argument is an interible collection?

[Charles Krug]

List:

I'm working on some methods that operate on (mathematical) vectors as
in:

def Convolution(x, y)
"""Returns a list containing the convolution of vectors x and y"""

Is there any way to determine at runtime that x and y are iterible
collections?

Do I *coughs* simply *coughs* trap the exception created by:

    for v in x:

when v is a scaler quantity?

Thanks
