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")89[ { ‘id’: 82, ‘name’: “Bob” }, { ‘id’: 83, ‘name’: “Amy” } ]AmyNothingBob
Solution
The code prints "Amy".
Here's the step-by-step explanation:
-
a = { 'id': 89, 'name': "John", 'projects': [1, 2, 3, 4], 'friends': [ { 'id': 82, 'name': "Bob" }, { 'id': 83, 'name': "Amy" } ] }- This line of code creates a dictionaryawith four keys: 'id', 'name', 'projects', and 'friends'. The 'friends' key has a value which is a list of dictionaries. -
a.get('friends')- This line of code retrieves the value of the 'friends' key in the dictionarya, which is a list of dictionaries. -
a.get('friends')[-1]- This line of code retrieves the last dictionary in the list of dictionaries, which is{ 'id': 83, 'name': "Amy" }. -
a.get('friends')[-1].get("name")- This line of code retrieves the value of the 'name' key in the last dictionary in the list, which is "Amy".
So, the code prints "Amy".
