In Python 2.2 you (at least in many cases) can avoid to use apply in 
favour of the following
simpler syntax:

 >>> def echo(cry):
    print '***'+cry+'***'

   
 >>> sch = [(echo,'Spam!'), (echo, 'Ham!')]
 >>> for (func, arg) in sch:
    print func, arg
    func(arg)

   
<function echo at 0x0093EBB0> Spam!
***Spam!***
<function echo at 0x0093EBB0> Ham!
***Ham!***
 >>>

Less hard to follow?
