Question

BMI Calculator code
#Unknown error in line 6
weight = float(input(''))
height = float(input(''))
bmi = weight/(height*height)
if (bmi < 18.5):
print ('Underweight')
elif (bmi >= 18.5 and < 25):
print ('Normal')
elif (bmi >= 25 and < 30):
print ('Overweight')
elif (bmi <= 30):
print ('Obesity')

Answer 1

hi! try to place all the ifs and elifs in one column strictly under each other. in python, spaces have values

Answer 2

after the logical "and" operator, you need to substitute a variable with which you compare the number 25

Answer 3

Or use this way:
(18.5 <= bmi < 25)

Answer 4

New error, line 5
