Question

I have a function like this one:

def hexify_string(aString):
    #code for string2hexa conversion

…and I want to have a function who accepts one or more (quantity undefined) parameters, and to return the hexadecimal representation of the sum of the parameters.

def hexify(a,b...n):
    #map hexify_string to all the parameters, and return the sum of them

Is there a way of doing this using *args / **kwars?

Answer 1

*args takes all non-keyword parameters and turns them into a list. You can map hexify_string to each element of the list, and then return the sum of all the elements in the list.

def hexify(*args);
    return sum(map(hexify_string, args)

This is assuming your hexify_string function returns a hex value, not a string.
