Question

使用教科书和代码课程学习Python。

此代码返回SyntaxError。我不能在同一elif语句中使用两个大于/小于符号吗？还是我的问题<< ='？

def movie_rating(rating):
    if rating <= 5:
        return "Avoid"
    elif rating > 5 and <= 9:
        return "I recommend!"
    else:
        return "Amazing"

Answer 1

The problem is because of your and in line 4, this error happening because when you use and you need to define a new condition in other word you should change your code to one of this codes:

def movie_rating(rating):
    if rating <= 5:
        return "Avoid"
    elif rating > 5 and rating <= 9:
        return "I recommend!"
    else:
        return "Amazing"

or change your code to this:

def movie_rating(rating):
    if rating <= 5:
        return "Avoid"
    elif 5> rating <= 9:
        return "I recommend!"
    else:
        return "Amazing"
