在python中从列表构建嵌套字典

# 创建一个包含字典的列表
data = [
    {"name": "Alice", "age": 25, "city": "New York"},
    {"name": "Bob", "age": 30, "city": "San Francisco"},
    {"name": "Charlie", "age": 35, "city": "London"}
]

# 构建嵌套字典
nested_dict = {}
for item in data:
    name = item["name"]
    nested_dict[name] = {
        "age": item["age"],
        "city": item["city"]
    }

# 打印嵌套字典
print(nested_dict)

{
    "Alice": {"age": 25, "city": "New York"},
    "Bob": {"age": 30, "city": "San Francisco"},
    "Charlie": {"age": 35, "city": "London"}
}
