输入语文成绩、数学成绩、英语成绩，计算出平均成绩，评定成绩等级。请使用f-string进行输出，并在f-string中对平均成绩保留1位小数。 优秀：90<= score <=100 良好：80<= score < 90 中等：60<= score < 80 较差：0<= score < 60

好的，我可以回答这个问题。以下是代码：

chinese_score = float(input("请输入语文成绩："))
math_score = float(input("请输入数学成绩："))
english_score = float(input("请输入英语成绩："))

average_score = (chinese_score + math_score + english_score) / 3
grade = ""

if 90 <= average_score <= 100:
    grade = "优秀"
elif 80 <= average_score <
