如何获取每种类型属性的均值字典

# 数据集
data = [
    {"type": "A", "value": 10},
    {"type": "A", "value": 20},
    {"type": "B", "value": 30},
    {"type": "B", "value": 40},
    {"type": "C", "value": 50},
    {"type": "C", "value": 60}
]

# 属性分类
type_dict = {}
for item in data:
    attr_type = item["type"]
    attr_value = item["value"]
    if attr_type in type_dict:
        type_dict[attr_type].append(attr_value)
    else:
        type_dict[attr_type] = [attr_value]

# 计算均值
mean_dict = {}
for attr_type, attr_values in type_dict.items():
    mean_value = sum(attr_values) / len(attr_values)
    mean_dict[attr_type] = mean_value

# 打印均值字典
print(mean_dict)

{'A': 15.0, 'B': 35.0, 'C': 55.0}
