How do I access nested collections in Python?
You can access nested collections like lists and dictionaries using indexing and keys. Can you provide an example?
Sure! I have a dictionary with lists inside it. How do I get a specific item?
You can access it by chaining the keys and indices. For example, if you have data = {'key': [1, 2, 3]}
, use data['key'][1]
to get 2
.
What if I have a list of dictionaries?
You can loop through the list and access each dictionary's keys. For example, for item in list_of_dicts: print(item['key'])
