1 没有转数据类型

2 直接在case里用比较运算会报错

heigh = float(input("身高(m): "))

weigh = float(input("体重(kg): "))

bmi = weigh / (heigh**2)

match bmi:

    case _ if bmi <= 18.5:

        print("过轻")

    case _ if 18.85 <= bmi <= 25:

        print("正常")

    case _ if 25 <= bmi <= 28:

        print("超重")

    case _:

        print("肥胖")
