How to add key value from a dictionary into a new dictionary after looping over in python

Question

I have tried looping through this list and the dictionary at its index. I intend to get the key-value pairs into a new dictionary.

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

new_dict = {}
for key in travel_log[0]:
    new_dict = key
print(new_dict)

The code above just loops into it and adds the last key looped over to the new dictionary, meanwhile, I want all the key values "countries", "visits" and "cities" to be there.

travel_log is a list of dictionaries list(dict()) if want to copy the first element of the travel_log to a new dictionary then do this:

new_dict = travel_log[0]

upd: as Serge Ballesta noticed below, the dictionary is a mutable data type; In oder to create a new object you can use dict()

new_dict = dict(travel_log[0])

Try this

new_dict = {}
for key,value in travel_log[0].items():
    new_dict[key] = value
print(new_dict)

Output

{'country': 'France',
 'visits': 12,
 'cities': ['Paris', 'Lille', 'Dijon']}
