[solved]My bmi calculator gives an error saying line 6 Expected an indented block..it's not .

Question

#your code goes here
weight = float(input())
height = float(input())
bmi= 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')
else bmi>=30:
print('obesity')

Answer 1

indentation is very important in python: that's what determine where a code block start and end (while most of other languages uses curly brackets do delimit them -- indentation is then optionnal but recommended for readability) ^^

also indentation must be consistent: if you use tabs, you must have only tabs, if you prefere x spaces, you must use same x numbers of spaces...

an if..else statement should look like:

if condition:
# line of code
# line of code
else:
# line of code
# line of code

even if you're not required to use same spacement for different blocks, it is highly recommanded ;)

Answer 2

anyway, you don't need to check values previously checked:

first if test for bmi<18.5

so if that the case, the related block will be executed and other elif/else where never reached.

if that's not the case, next elif could only test if bmi<25, because you are sure that bmi>=18.5 is True ^^

... and so on for next all elif ;P

Answer 3

wich is the line 11 in your source?

Answer 4

oh, I see:

the last else do not have a condition ^^

Here is some mistakes in your code:

1 - Indentation is very important in python
2 - else never has condition, else only has expression
3 - First letter should be Capital of each word.

Here is solution:

#your code goes here
weight = float(input())
height = float(input())

bmi = 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')
else:
print('Obesity')

#Now saying that try again then only u can become a good coder

Answer 6

Yes it's done now only one thing was getting wrong which u mentioned above that it should be in capital and the code runned..😃😃yipeeeee....thanks to u all for helping me out and finding me what's mistake is being done by me...

Answer 7

BTW I am a beginner too!
Just writing my views here buddy! I hope you will fine some help with it.

You haven't indented anything in your code my friend.
In python, indentation is very very important, it defines, the blocks of a condition,
So you need to indent the each print statement under any condition in your code!

I.e
#your code goes here

weight = float(input())
height = float(input())
bmi = 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')
else:
print('obesity')

1 more thing to explain here, when each of the about four conditions doesn't met, then all the remaining conditions will come automatically under the 'else' statement, you don't need to put a condition there! Like in your case you had written (else bmi>=30)! There is no need for it!

You can add [SOLVED] before the question.

Answer 9

So sir/ mam what should I do to run my code..i mean that can't I use elif statement instead of writing else if separately as I have written.

Answer 10

add spacing to the lines related to if, elif and else ;P

Answer 11

weight = float(input())
height = float(input())
bmi= 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')
else:
print('obesity')

Answer 12

Okk I will try once again..

Answer 13

weight = float(input())
height = float(input())
bmi= 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')
else bmi>=30:
print('obesity')
I made changes with spacing that issue is solved but now it's saying invalid syntax for line 11

Answer 14

Else bmi >=30

Answer 15

that's what I said ;P

(don't forgot that pyrhon is case sensitive and 'else' must be all lowercased -- I guess it is capitalized un your last post because of your phone)

Answer 16

But I have written that else bmi >=30:

Answer 17

No no in code it's in lowered case else...I m sorry that I m disturbing u this time.

Answer 18

yes, you must write only:

else:

(I will edit my previous post where I have just copied pasted your code and only add spaces)

Answer 19

Still showing the same error on line 11..

Answer 20

it must run fine now...

are you sure to have put the colon after 'else' ?
