如何对每个元素进行分组并按最大值排序

# 示例数据
elements = [
    {'name': 'A', 'value': 10},
    {'name': 'B', 'value': 5},
    {'name': 'C', 'value': 15},
    {'name': 'D', 'value': 8},
    {'name': 'E', 'value': 15},
    {'name': 'F', 'value': 3}
]

# 分组
groups = {}
for element in elements:
    value = element['value']
    if value not in groups:
        groups[value] = []
    groups[value].append(element)

# 找到每个分组中的最大值
max_values = []
for value, group in groups.items():
    max_value = max(group, key=lambda x: x['value'])
    max_values.append(max_value)

# 按最大值进行排序
sorted_elements = sorted(max_values, key=lambda x: x['value'], reverse=True)

# 输出结果
for element in sorted_elements:
    print(element)
