so currently im working on a function where you add countries you visit, times visited and cities visited to a list however whenever i add the arguments to the list through the function i get a type error

code

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