feature.  It is called a keyword argument.

def func(a, b, c):
        print a
        print b
        print c

func(b = 1, a = 8, c = 'hello')

The idea here is you can call the function with the arguments in any order as
long as you know their names.  Hnady for long function calls like gui toolkits
or network code.
