如何在列表中的字典中检索列表？

Question

How do I retrieve a list value, within a dictionary, that's within a list?

x = [{'name': 'joe', 'items': ['hat','scarf','boots']},
{'name': 'john', 'items': ['jeans','shirt','jacket']}]

x is considered a list type variable, and I'm trying to pull just the values within the list called 'items'.

Calling x[0] will load the first list item which includes name and items for joe, but not sure how to pull only the items. x[0][0] of course doesn't work because it's also part of a dictionary.

Answer 1

你是这个意思吗？：

x[0]['items']

Answer 2

You access it just as you would think intuitively. Access the first element in your list, and then the list element at index 0 for your respective dict:

>>> print(x[0]['items'][0])
hat

The logical progression

>>> print(x[0])
{'name': 'joe', 'items': ['hat', 'scarf', 'boots']}

>>> print(x[0]['items'])
['hat', 'scarf', 'boots']

>>> print(x[0]['items'][0])
hat
