In Python, the `else` statement can be used with a `for` loop. The `else` block executes when the loop completes all its iterations without being interrupted by a `break` statement. This feature is particularly useful for confirming that the loop ran to completion.

Let's adapt this concept to the `travel_list`. We'll print each destination, and when all destinations are processed without interruption, the `else` block will confirm completion.

travel_list = ['Monako', 'Luxemburg', 'Liverpool', 'Barcelona', 'Munchen']

# Printing all destinations
for city in travel_list:
    print(city)
else:
    print('All destinations have been listed.')

Now, let's add a condition to terminate the loop prematurely using `break`. If we're looking for a specific city (e.g., `'Barcelona'`) and find it, the loop stops, and the `else` block does not execute.

travel_list = ['Monako', 'Luxemburg', 'Liverpool', 'Barcelona', 'Munchen']

# Searching for a specific city
for city in travel_list:
    print(city)
    if city == 'Barcelona':
        break
else:
    print('All destinations have been listed.')

In this case, the `else` block does not execute because the loop was interrupted with `break`. You can use `not in` to confirm that a city is absent from the list. If the city is not found in the list, we can execute specific actions.

travel_list = ['Monako', 'Luxemburg', 'Liverpool', 'Barcelona', 'Munchen']

# Checking if a city is NOT in the list
search_city = 'Paris'

if search_city not in travel_list:
    print(search_city, 'is not in the travel list.')
else:
    print(search_city, 'is in the travel list.')

The `not in` operator checks whether an element is not present in a collection (like a list, tuple, or string). Use it to check whether a city is not in the `favorite_city` list.
