varargs

varargs is short for variable arguments. It is declared like this:

def print_person_varargs(name, *vargs): 
    pass

You can pass as many arguments as you like. In this case we pass two after the first positional argument ‘name:’

print_person_varargs("Jörn", 40, "Emskirchen")

What can you do with it now?

def print_person_varargs(name, *vargs): 
    print(vargs) 
    for arg in vargs: 
        print(arg)

varargs are combined to a tuple. so it is possible to iterate over them

kwargs

def print_person_kwargs(name, **kwargs): 
    pass

kwargs stands for keyword arguments. you have to pass them as named parameters into a function like this:

print_person_kwargs("Jörn", age=40, city="Emskirchen")

They evaluate to a dictionary so you can iterate as well and access the keys and the values:

def print_person_kwargs(name, **kwargs): 
    print(kwargs) 
    for i, j in kwargs.items(): 
        print(i, j)
