I'm not sure what you mean by 'get posted'
It is activated once the function is called.
ie
def foo(x):
return 2 + x
does nothing until I call it:
result = foo(5)
print result
def calc_BMI(weight,height):
if bmi <=18.5:
return 'underweight'
Since BMI is a value your function is better as it was, just returning
the value.
The code to convert that BMI value into a weight assessment is better
done outside, again as you had before. (Or inside another function,
rateBMI(bmi) maybe)
What was missing was some glue that joins those 2 things together:
read weight and height
call CalcBMI
use result to assess weight.
elif bmi >= 18.5 and bmi <=24.9:
return 'normal weight'
BTW in Python you can abbreviate the tests slightly with
elif 18.5 <= bmi <= 24.9:
print 'normal weight'
