# 代码块 Demo

顶部更矮；顶部和代码区同色；只用一条细线分割；不添加不存在的功能。

示例代码块：

Python

    import random
    from datetime import datetime

    quotes = [
        "Stay curious.",
        "Code is poetry.",
        "Small steps every day.",
        "Debugging is detective work.",
    ]

    def random_quote():
        now = datetime.now().strftime("%Y-%m-%d %H:%M:%S")
        quote = random.choice(quotes)
        return f"[{now}] {quote}"

    if __name__ == "__main__":
        for i in range(3):
            print(random_quote())
