Answer 1

weight = int(input())
height = float(input())

# create a variable for easy usabilty

bmi = weight/(height*height)
if bmi <= 18.5:
print("Underweight")

# there should bmi on both sides of operators
elif 18.5<=bmi<25:
print("Normal")

elif 25<=bmi<30:
print("Overweight")

elif bmi >30:
print("Obesity")

This should help

Answer 2

use declared variable instead of everytime to write
weight/(height*height)
bmi = weight/(height*height)

Answer 3

Thank you! That makes so much more sense!
