How do I work with nested data structures in Python 3?
In Python 3, nested data structures can include lists, dictionaries, or a combination of both. What specific structure are you interested in?
Can you give me an example of a nested dictionary?
Sure! Here's an example: data = {'person': {'name': 'Alice', 'age': 30}, 'city': 'Wonderland'}
. You can access the name with data['person']['name']
.
How can I loop through a nested list?
You can use a nested loop. For example: for sublist in nested_list: for item in sublist: print(item)
.
What about modifying values in a nested structure?
You can modify values by accessing them directly. For example, data['person']['age'] = 31
updates Alice's age.
