Adding a dictionary to a list through a function

So I have been practicing some coding in Python. I came to a task where I was supposed to add a dictionary to an existing list (which had dictionaries).

The given function (at the end) works, but when I tried to write the following (in the function)

    travel_log.append(add_new_country)

instead of

    travel_log.append(country)
    travel_log.append(visits)
    travel_log.append(cities)

and then try to print out travel_log, I would get the following (look at the last dictionary in the list):

[{'country': 'France', 'visits': 12, 'cities': ['Paris', 'Lille', 'Dijon']}, {'country': 'Germany', 'visits': 5, 'cities': ['Berlin', 'Hamburg', 'Stuttgart']},<function add_new_country at 0x7fefd60e8310>]

Can somebody explain why does that happen?

Full code:

    travel_log = [
    {
    "country": "France",
    "visits": 12,
    "cities": ["Paris", "Lille", "Dijon"]
    },
    {
    "country": "Germany",
    "visits": 5,
    "cities": ["Berlin", "Hamburg", "Stuttgart"]
    },
    ]


    def add_new_country(country,visits,cities):
    travel_log.append(country)
    travel_log.append(visits)
    travel_log.append(cities)

    add_new_country("Russia", 2, ["Moscow", "Saint Petersburg"])
    print(travel_log)

>Solution :

You need to create a dictionary and add it to travel_log (list),

def add_new_country(country,visits,cities):
    d = {'country': country, 'visits': visits, 'cities': cities}
    travel_log.append(d)
