Why my code is not working

Question

w= int(input())
h= input()
bmi= w / ((h)**2)

if bmi > 18.5:
print("Underweight")
if bmi >=25:
print("Normal")
if bmi >=30:
print("overweight")
else:
print("obesity")

Answer 1

second input is of float type input, you need to convert to float otherwise it's error.
Use
h = float( input() )

You need to learn about indentation well in python.

If bmi is <18.5 , your code put no output.
If input is >=30 ex: 35 then it outputs

Underweight
Normal
Overweight

3 outputs. wrong answer. so it needs proper indentation.
