这是代码:

Weight = float(input("Enter weight in Kilograms: "))
Height = float(input("Enter height in meters: "))
BMI = (Weight / (Height**2))
print ("%.2f" %BMI)
if BMI < 18.5:
    print ("You are under weight")
elif BMI >= 18.5 and < 25.0:
    print ("You weight is normal")
elif BMI >= 25.0 and < 30.0:
    print ("You are overweight")
elif BMI >= 30.0:
    print ("You are overweight")


在线获取无效语法
elif BMI> = 18.5且

最佳答案

><和其他都是二进制运算符。它在每一侧寻找一个操作数,当它在左侧找到一个关键字时,and < 25.0会抛出一个SyntaxError

正常的方法是:

if BMI >= 18.5 and BMI < 25.0:


但是,存在不平等的捷径:

if BMT < 18.5:
    # underweight
elif 18.5 <= BMI < 25.0:
    # normal
elif 25.0 <= BMI < 30:
    # overweight
elif 30 <= BMI:
    # super overweight
