Can a variable number of arguments be passed to a function?

Question

In a similar way to using varargs in C or C++:

fn(a, b)
fn(a, b, c, d, ...)

Answer 1

def f(dic):
    if 'a' in dic:
        print dic['a'],
        pass
    else: print 'None',

    if 'b' in dic:
        print dic['b'],
        pass
    else: print 'None',

    if 'c' in dic:
        print dic['c'],
        pass
    else: print 'None',
    print
    pass
f({})
f({'a':20,
   'c':30})
f({'a':20,
   'c':30,
   'b':'red'})
____________

the above code will output

None None None
20 None 30
20 red 30

This is as good as passing variable arguments by means of a dictionary
