 4 self.next_id = 0
 5
 6 def add_memory(self, user_input, ai_response, timestamp):
 7 memory_entry = {
 8 "id": self.next_id,
 9 "user_input": user_input,
10 "ai_response": ai_response,
11 "timestamp": timestamp
12 }
13 self.memory[self.next_id] = memory_entry
14 self.next_id += 1
15 print(f"Memory added: ID {memory_entry['id']}")
16
17 def retrieve_recent_memories(self, count=5):
18 if not self.memory:
19 return "No memories found."
20
21 sorted_keys = sorted(self.memory.keys(), reverse=True)
22 recent_keys = sorted_keys[:count]
23 recent_memories = [self.memory[key] for key in recent_keys]
24
25 print(f"Retrieved {len(recent_memories)} recent memories.")
26 return recent_memories
27
28 def retrieve_memory_by_keyword(self, keyword):
29 matching_memories = []
30 for memory in self.memory.values():
31 if keyword.lower() in memory["user_input"].lower() or keyword.lower() in memory["ai_response"].lower():
32 matching_memories.append(memory)
33
34 print(f"Found {len(matching_memories)} memories related to '{keyword}'.")
35 return matching_memories
36
37## To run this code:
38## 1. Ensure you have Python installed.
39## 2. Save the code as a Python file (e.g., memory_sim.py).
