Why "invalid syntax"?

Question

I don't why it keeps telling me that line 4 of my code is "invalid syntax":

weight = int(input())
height = float((input())
BMI = weight / (height ** 2)
if BMI < 18.5:
print("Underweight")
elif 18.5 <= BMI < 25:
print("Normal")
elif 25 <= BMI < 30:
print("Overweight")
else:
print("Obesity")
