Hello all,
I'm new to python and its been a stuggle so far. I'm attempting to
create a BMI calculator in Wing 101 4.1. I keep getting syntax errors:
def calc_BMI(weight,height):
return (weight/(height*height))*703.0
if bmi <=18.5:
print 'underweight'
elif bmi >= 18.5 and bmi <=24.9:
print 'normal weight'
elif bmi >=25 and bmi <=29.9:
print 'overweight'
elif bmi >=30:
print 'obese'
Also, height should be converted to inches and I have not the
slightest clue how to so. Any help would be much appreciated.

If you're using Python 3 you'll get syntax errors as print is a
function, not a statement as in Python 2. Is this your problem? If not
please cut and paste the exact syntax error for us to see. Then we'll
sort the rest of the problems :)
As Mark implies, tell us exactly what Python version you're using, and
copy/paste the entire error message, including traceback.
For example, when I run it on 3.3, I have:
davea@think2:~/temppython$ python3.3 soliman.py
File "soliman.py", line 6
print 'underweight'
^
SyntaxError: invalid syntax
Also, could you tell us your experience level? You've defined a
function, but you haven't called it. And yet you're apparently trying
to use the results of calling it.
As for converting height to inches, that depends on what you started
with. Since you're using the English version of the formula, you should
already have inches and pounds before calling that function.
So perhaps in addition to missing the code for inputting the values
(perhaps the raw_input function), you're also missing the conversion
from "something" to inches. How are you getting the raw numbers, and
what units are they in?
If the raw numbers are in meters and kg, then you'd want to remove the
multiply by 703. Or you could convert from meters to inches by
multiplying by 39.? (look up the exact number). And from kg to pounds
by a similar multiply by something like 2.2
