 Now write another function called `next_up` that returns our first destination (the destination with the lowest index), in the `travel_destinations` list.

 Ok, now write a function called `favorite_destination` that returns the string `'madagascar'`.
 
 
 ```python
 travel_destinations = ['argentina', 'mexico', 'italy', 'finland', 'canada', 'croatia']
 def favorite_destination():

 Again, let's declare an array called `travel_destinations`. Change the function `favorite_destination` so that it continues to return the string `'madagascar'`, but also adds the string `'madagascar'` to the end of the list of destinations.

 Now let's write another function which iterates through the list of `destinations` and capitalizes the first letter of each word. It should return a list of capitalized destinations.
 
 
 ```python
 travel_destinations = ['argentina', 'mexico', 'italy', 'finland', 'canada', 'croatia']
 def capitalize_countries():
-    capitalized_countries = []
-    for destination in travel_destinations:
-        capitalized_countries.append(destination.title())

 ```

 Great! Now if someone adds a country that is lowercased to our list of destinations, we can simply call our function again to capitalize each of the destinations in the list.

 ## Summary
 
 Great job! In this lab we were able to get practice both writing and returning values from functions. We also practiced accessing variables not local to the function but in the global scope.
