**kwargs

When it iterating over a dictionary you are only able to iterate over 
the keys not the values. The ** when placed before a variable will allow
you to iterate and unpack both key and value pairs. Because you are 
unpacking both key and value this will return the result as a dictionary.

def myFun(*args,**kwargs):
    print("args: ", args)
    print("kwargs: ", kwargs)
 
 
# Now we can use both *args ,**kwargs to pass arguments to this function :
myFun('geeks','for','geeks',first="Geeks",mid="for",last="Geeks")

# Python program to illustrate  **kargs for 
# variable number of keyword arguments with
# one extra argument.
 
def myFun(arg1, **kwargs): 
    for key, value in kwargs.items():
        print ("%s == %s" %(key, value))
 
# Driver code
myFun("Hi", first ='Geeks', mid ='for', last='Geeks')    

def myFun(arg1, arg2, arg3): 
    print("arg1:", arg1) 
    print("arg2:", arg2)

# Now we can use *args or **kwargs to 
# pass arguments to this function :
