我有以下的dicts列表.
people = [
{'name': "Tom", 'age': 10},
{'name': "Mark", 'age': 5},
{'name': "Pam", 'age': 7}
]
对于在dicts列表中搜索的性能而言,这将是最优化的方式.以下是一些不同的方法:
next((item for item in dicts if item["name"] == "Pam"), None)
要么
filter(lambda person: person['name'] == 'Pam', people)
要么
def search(name):
for p in people:
if p['name'] == name:
return p
要么
def search_dictionaries(key, value, list_of_dictionaries):
return [element for element in list_of_dictionaries if element[key] == value]
任何其他方法也欢迎.谢谢.
