def print_dict(**person):
        print(person)

print_dict( a ='jack', b ='rose')
# {'a': 'jack', 'b': 'rose'}

With two asterisks, Python will create a dictionary to hold the keywords arguments. What I do not understand is why the arguments are: a = "Jack" instead of "a" = "Jack", cause a is a key, why is it not quoted?

    No, `a` is the name of a function argument, not a dictionary key. `d['a']` and `{'a': ...}` are dictionary keys. – deceze Mar 06 '18 at 11:49

  • You can use `print_dict(**{'a': 'jack', 'b': 'rose'})` and get the same result, you don't have to pass it as function arguments. – user3483203 Mar 06 '18 at 11:51
