BMI calculator

Question

I am a beginner at Python

At this test

I want to use While loop

like this:

h = float(input())
w = float(input())
while BMI = w / h**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')
break

But the error message appears:
while BMI = w / h**2:
^
SyntaxError: invalid syntax

where is the wrong??

Answer 1

Why you need loop there?
Remove it. And just use
BMI = w/ h**2
looks like first input, second inputs are swapped.! do check again.

Answer 3

You are using the assignment operator (=), you want to use (==) which does comparisons for equality.

Answer 4

I tried use (==) but the same error appears 😕

Answer 5

Can you share you updated code as a code bit (not just text so it's easier to debug)?

Answer 6

I solved it

Answer 7

I was forgetting to capitalize the strings and that was my problem

weight = float(input())
height = float(input())
bmi = weight / (height * height)
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")
