Python列表的字典搜索 [英] Python list of dictionaries search

问题描述

假设我有这个：

[
{"name": "Tom", "age": 10},
{"name": "Mark", "age": 5},
{"name": "Pam", "age": 7}
]

并通过搜索Pam作为名称，我想检索相关的字典：{name：Pam年龄：7}

and by searching "Pam" as name, I want to retrieve the related dictionary: {name: "Pam", age: 7}

如何实现？

推荐答案

你可以使用生成器表达式：

>>> dicts = [
...     { "name": "Tom", "age": 10 },
...     { "name": "Mark", "age": 5 },
...     { "name": "Pam", "age": 7 },
...     { "name": "Dick", "age": 12 }
... ]

>>> (item for item in dicts if item["name"] == "Pam").next()
{'age': 7, 'name': 'Pam'}
