Why did the code cause the error? I don't see any mistakes.

Question

вес = int(input())
рост = int(input())
if вес / рост**2 < 18.5:
print("Underweight")
elif вес / рост**2 >= 18.5 and вес / рост**2 < 25:
print("Normal")
elif вес / рост**2 >= 25 and вес / рост**2 < 30:
print("Overweight")
elif вес / рост**2 >= 30:
print("Obesity")

Answer 1

ВСЯКОЧИНИ ,

one hint to this code:
the suggested code has some *redundant* parts:  

>  вес / рост**2 

is calculated in each conditional case, in total it does 6 times the same. so better to do the calculation once, store it in a variable and use this variable instead:

вес = float(input())
рост = float(input())
bmi = вес / рост**2 # <= added this line to calculate the bmi
if bmi < 18.5: # <= modified this line
    print("Underweight")
elif bmi >= 18.5 and bmi < 25: # <= modified this line
    print("Normal")
elif bmi >= 25 and bmi < 30: # <= modified this line
    print("Overweight")
elif bmi >= 30: # <= modified this line
    print("Obesity")

Answer 2

ВСЯКОЧИНИ the data type for рост should be float, not int. Converting the input to int causes it to lose the decimal portion of the input value.

Answer 3

ВСЯКОЧИНИ the data type in your code is wrong, you wrote int but it will be float | int= integer value, float=decimal value

Code will be:-

вес = float(input())
рост = float(input())
if вес / рост**2 < 18.5:
print("Underweight")
elif вес / рост**2 >= 18.5 and вес / рост**2 < 25:
print("Normal")
elif вес / рост**2 >= 25 and вес / рост**2 < 30:
print("Overweight")
elif вес / рост**2 >= 30:
print("Obesity")

Thank you all. Apparently at night I'm really dumb
