Conversation History Builder
Build a conversation history list — the same {"role": ..., "content": ...} structure every chat-based AI API expects — from a system prompt and an alternating sequence of user/assistant messages.
Approach: start the history with the system message, then append each given message, alternating role "user" then "assistant" as the notes' own chatbot pattern does.
Input: First line: the system prompt. Second line: how many messages follow, n. Next n lines: the messages, alternating user then assistant.
Output: One line per history entry (n + 1 total): the entry as a Python dict.
You are helpful. 2 Hi Hello!
{'role': 'system', 'content': 'You are helpful.'}
{'role': 'user', 'content': 'Hi'}
{'role': 'assistant', 'content': 'Hello!'}- 0 <= n <= 20
Hint 1
The system message always comes first, with role "system".
Hint 2
Even-indexed turns (0, 2, 4, ...) are from the "user"; odd-indexed turns are from the "assistant" — i % 2 == 0 checks this.
Hint 3
Each entry is a dict: {"role": role, "content": message}.
The history always starts with one system-role entry. Looping over the given turns with enumerate(), even indices (0, 2, 4, ...) are labeled "user" and odd indices "assistant" (i % 2 == 0), matching a normal back-and-forth conversation — exactly the {"role": ..., "content": ...} list structure the notes show being resent on every API call.
