Question
What do these lines print?>>> a = { 'id': 89, 'name': "John", 'projects': [1, 2, 3, 4], 'friends': [ { 'id': 82, 'name': "Bob" }, { 'id': 83, 'name': "Amy" } ] }>>> a.get('friends')[-1].get("name")
Solution
The lines of code are written in Python. They define a dictionary a with several key-value pairs. The key 'friends' has a list of dictionaries as its value. Each dictionary in the list represents a friend with an 'id' and a 'name'.
The line a.get('friends')[-1].get("name") does the following:
-
a.get('friends')retrieves the value of the key 'friends' from the dictionarya. This value is a list of dictionaries. -
[-1]gets the last item in this list. This item is a dictionary representing the last friend in the list. -
.get("name")retrieves the value of the key 'name' from this dictionary.
So, the lines print the name of the last friend in the list, which is "Amy".
