Question

BMI = float(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")
elif BMI > 30 :
print ("Obesity")

Answer 1

blocks are the problem ....
(note : the spacing is very important)
weight = float(input())
height = float(input())
BMI = float(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")
elif BMI > 30 :
print ("Obesity")

Answer 2

# Indentation is a way to highlight blocks of code in Python to get Python to work and increase the readability.

# According to PEP 8, spaces are prefered over tabs as indentation method, and 4 spaces should be used per indentation level. Example:

if alpha >= 0:
do_this()
print(”It’s done!”)
else:
do_that()
if beta < 0:
do_that_too()
print(”That too is now done!”)
print(”Program ends.”)

# This will increase the readability.
