Question

userRate :: Film -> Float
userRate (_,_,_,[],[]) = 0
userRate (_,_,_,likes,dislikes) = fromIntegral(length likes)/fromIntegral(length likes + length dislikes)* 100

---圆形用户评分的功能

websiteRating :: Film -> Int
websiteRating film = round(userRate (film))

- 函数使用列表推导来过滤网站评级为75及以上的电影

rating:: [Film] -> [Film]
rating films = [ film | film <-films , websiteRating film >=75]

我创建了一个功能，它给了我一个电影列表，只有那些显示网站评分高于75的电影，但我想在电影旁边添加网站评级

例如，这是显示的内容

Title: Silence
Director: Martin Scorsese
Year:2016
Website Rating : 76



Title: The Terminal
Director: Steven Spielberg
Year:2004
Website Rating : 76%

我想在列表中显示网站评级，我该怎么做？感谢

也许你正在寻找这样的东西，整个结果是一组由电影和评级组成的对。
