如何对字典列表进行排序？

# 定义一个字典列表
people = [
    {"name": "John", "age": 25, "city": "New York"},
    {"name": "Emily", "age": 30, "city": "London"},
    {"name": "Daniel", "age": 20, "city": "Paris"}
]

# 根据键"age"对字典列表进行排序
sorted_people = sorted(people, key=lambda x: x["age"])

# 打印排序后的结果
for person in sorted_people:
    print(person)

{'name': 'Daniel', 'age': 20, 'city': 'Paris'}
{'name': 'John', 'age': 25, 'city': 'New York'}
{'name': 'Emily', 'age': 30, 'city': 'London'}
