Question

我是新手，我在完成一部分作业时遇到了一些问题。基本上我有2个列表：

names = ["Jerry", "Fernando", "Radu", "Juan", "Brie", "Dani", "Fallon", "Nina", "Max", "Mike", "Johnny", "Saul", "Simon", "Billy"]
ages = [27, 27, 23, 27, 27, 23, 33, 32, 25, 32, 26, 26, 29, 24]

我想要实现的是一本看起来像这样的词典：

{'Jerry': {'age': 27},
 'Fernando': {'age': 27},
 # ...
 'Billy': {'age': 24},
}

我使用元组来显示它[('Jerry', 27), ('Fernando', 27), ..., ('Billy', 24)]，但我无法弄清楚如何在字典中显示它，每个键值都在新行上。

Answer 1

使用词典理解：

{name: {'age': age} for name, age in zip(names, ages)}

演示：

>>> from pprint import pprint
>>> names = ["Jerry", "Fernando", "Radu", "Juan", "Brie", "Dani", "Fallon", "Nina", "Max", "Mike", "Johnny", "Saul", "Simon", "Billy"]
>>> ages = [27, 27, 23, 27, 27, 23, 33, 32, 25, 32, 26, 26, 29, 24]
>>> {name: {'age': age} for name, age in zip(names, ages)}
{'Mike': {'age': 32}, 'Simon': {'age': 29}, 'Johnny': {'age': 26}, 'Max': {'age': 25}, 'Juan': {'age': 27}, 'Jerry': {'age': 27}, 'Fernando': {'age': 27}, 'Nina': {'age': 32}, 'Billy': {'age': 24}, 'Radu': {'age': 23}, 'Dani': {'age': 23}, 'Fallon': {'age': 33}, 'Brie': {'age': 27}, 'Saul': {'age': 26}}
>>> pprint(_)
{'Billy': {'age': 24},
 'Brie': {'age': 27},
 'Dani': {'age': 23},
 'Fallon': {'age': 33},
 'Fernando': {'age': 27},
 'Jerry': {'age': 27},
 'Johnny': {'age': 26},
 'Juan': {'age': 27},
 'Max': {'age': 25},
 'Mike': {'age': 32},
 'Nina': {'age': 32},
 'Radu': {'age': 23},
 'Saul': {'age': 26},
 'Simon': {'age': 29}}

Answer 2

你可以压缩它：

dict(zip(names, ({'age': a} for a in ages)))

从两个列表创建字典
