Prepending / appending to *args

[Nikolai Kirsebom]

I think I've seen how this is done somewhere, but cannot find it.  Could
anyone show me how I in function A below add an argument at the beginning of
the list / at the end of the list which then is supplied to function B.


def A(*args):
  pa = 'prepended-argument'
  aa = 'appended-argument'
  B(pa+args+aa)   ''''SYNTAX here ??

def B(*args):
  for arg in args:
    print arg


A(1,2,3)
-----

Result should be:
'prepended-argument'
1
2
3
'appended-argument'

------------

Thanks for any help

Nikolai
