按对象数组中的公共属性对项进行分组

# 输入的对象数组
objects = [
    {"name": "Alice", "age": 25},
    {"name": "Bob", "age": 30},
    {"name": "Alice", "age": 35},
    {"name": "Charlie", "age": 40}
]

# 创建字典用于存储分组结果
groups = {}

# 遍历对象数组
for obj in objects:
    # 获取公共属性值
    name = obj["name"]
    
    # 将对象添加到分组
    if name in groups:
        groups[name].append(obj)
    else:
        groups[name] = [obj]

# 输出分组结果
for name, group in groups.items():
    print("Group: " + name)
    for obj in group:
        print(obj)

# 示例输出：
# Group: Alice
# {'name': 'Alice', 'age': 25}
# {'name': 'Alice', 'age': 35}
# Group: Bob
# {'name': 'Bob', 'age': 30}
# Group: Charlie
# {'name': 'Charlie', 'age': 40}
