Python:如何按相似键对字典列表进行排序

students = [
    {'name': 'Alice', 'score': 85},
    {'name': 'Bob', 'score': 92},
    {'name': 'Charlie', 'score': 78},
    {'name': 'David', 'score': 92}
]

# 按照分数升序排序
sorted_students = sorted(students, key=lambda student: student['score'])
print(sorted_students)

# 输出:
# [{'name': 'Charlie', 'score': 78}, {'name': 'Alice', 'score': 85}, {'name': 'Bob', 'score': 92}, {'name': 'David', 'score': 92}]

# 按照分数降序排序
sorted_students_desc = sorted(students, key=lambda student: student['score'], reverse=True)
print(sorted_students_desc)

# 输出:
# [{'name': 'Bob', 'score': 92}, {'name': 'David', 'score': 92}, {'name': 'Alice', 'score': 85}, {'name': 'Charlie', 'score': 78}]

# 先按分数降序排序，分数相同则按名字升序排序
sorted_students_multi = sorted(students, key=lambda student: (-student['score'], student['name']))
print(sorted_students_multi)

# 输出:
# [{'name': 'Bob', 'score': 92}, {'name': 'David', 'score': 92}, {'name': 'Alice', 'score': 85}, {'name': 'Charlie', 'score': 78}]
