20.Python Arbitrary Arguments

Python Arbitrary Arguments, *args 
    Arbitrary arguments are used when you are not sure about how many arguments will have to be passed into your function. In Python, it is possible to provide variable arguments in a function as parameters. The single asterisk form (*args) is used to pass a non-key worded, variable-length argument list, and the double asterisk form is used to pass a key worded, variable-length argument list. 

Program
def power(*x): 
    return (x[0]+x[2]-x[1]) 
a=power(108,4000,5) 
print(a) 
Output 
-3887 
Arbitrary Keyword Arguments, **kwargs 
    If you do not know how many keyword arguments that will be passed into your function, add two asterisk: ** before the parameter name in the function definition. 
Program 
def fruits(**fruit): 
    print("my favorite is: " + fruit["f1"]) 
    print("i hate: "+fruit["f3"]) 
fruits(f1 = "banana", f2 = "apple",f3="Mango") 
Output 
my favorite is: banana 
i hate: Mango
