# 单独的内存操作

这个示例展示了如何手动添加、检索、删除和替换用户记忆。

## 代码

```python cookbook/agent_concepts/memory/01_standalone_memory.py theme={null}
from agno.memory.v2 import Memory, UserMemory
from rich.pretty import pprint

memory = Memory()

# 为默认用户添加记忆
memory.add_user_memory(
    memory=UserMemory(memory="The user's name is John Doe", topics=["name"]),
)
print("Memories:")
pprint(memory.memories)

# 为 Jane Doe 添加记忆
jane_doe_id = "jane_doe@example.com"
print(f"\nUser: {jane_doe_id}")
memory_id_1 = memory.add_user_memory(
    memory=UserMemory(memory="The user's name is Jane Doe", topics=["name"]),
    user_id=jane_doe_id,
)
memory_id_2 = memory.add_user_memory(
    memory=UserMemory(memory="She likes to play tennis", topics=["hobbies"]),
    user_id=jane_doe_id,
)
memories = memory.get_user_memories(user_id=jane_doe_id)
print("Memories:")
pprint(memories)

# 删除记忆
print("\nDeleting memory")
memory.delete_user_memory(user_id=jane_doe_id, memory_id=memory_id_2)
print("Memory deleted\n")
memories = memory.get_user_memories(user_id=jane_doe_id)
print("Memories:")
pprint(memories)

# 替换记忆
print("\nReplacing memory")
memory.replace_user_memory(
    memory_id=memory_id_1,
    memory=UserMemory(memory="The user's name is Jane Mary Doe", topics=["name"]),
    user_id=jane_doe_id,
)
print("Memory replaced")
memories = memory.get_user_memories(user_id=jane_doe_id)
print("Memories:")
pprint(memories)
```
