我怎样才能得到一篇帖子的平均点赞？

def calculate_average_likes(posts):
    total_likes = sum(post['likes'] for post in posts)
    average_likes = total_likes / len(posts) if posts else 0
    return average_likes

# 假设有以下帖子数据
posts = [
    {'id': 1, 'likes': 100},
    {'id': 2, 'likes': 200},
    {'id': 3, 'likes': 150}
]

average = calculate_average_likes(posts)
print(f"Average likes per post: {average}")

function calculateAverageLikes(posts) {
    const totalLikes = posts.reduce((sum, post) => sum + post.likes, 0);
    const averageLikes = posts.length ? totalLikes / posts.length : 0;
    return averageLikes;
}

// 假设有以下帖子数据
const posts = [
    { id: 1, likes: 100 },
    { id: 2, likes: 200 },
    { id: 3, likes: 150 }
];

const average = calculateAverageLikes(posts);
console.log(`Average likes per post: ${average}`);
