#whats wrong please help
weight = float(input())
height = float((input())
BMI = weight / height * height
print(BMI)
if BMI < 18.5:
print("Underweight")
elif (18.5 <= BMI < 25):
print("Normal")
elif (25 <= BMI < 30):
print("Overweight")
else:
if BMI >= 30:
print("Obesity")
# #

Answer 1

#whats wrong please help
weight = float(input())
#There is an extra parenthesis
height = float(input())
#You need to use `**` operator instead of `*` since ** operator has higher precedence than *
BMI = weight / height ** 2
#print(BMI)
if BMI < 18.5:
print("Underweight")
elif (18.5 <= BMI < 25):
print("Normal")
elif (25 <= BMI < 30):
print("Overweight")
else:
if BMI >= 30:
print("Obesity")

Answer 2

Your comparison statements need to be adjusted.
Example:
elif BMI >= 18.5 < 25: # if BMI is greater than or equal to 18.5 but smaller than 25

Answer 4

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