Keyword arguments

For keyword arguments we need to use two asterisks (**) before the argument name.

All source code available on github

def addValue(**kwargs):
    total = 0
    for key, value in kwargs.items():
        print "Key",key,"value",value
        total += value
    return total


print "Total",addValue(item1=2, item2=3 ,item3=5, item4=7)

Output:

Key item2 value 3
Key item3 value 5
Key item1 value 2
Key item4 value 7
