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.

Hi,
I am also a newbie, but I wish to learn, so I offer the following
corrections.
Yes, as someone pointed out, it would be better if several of the print
statements were return, as corrected below.
# Note. I do note know what units you are using.
# I would use scientific, metric units. So you need to divide both
weight and height by a suitable conversion factors.
# Then you will not need the number 703.0, and the units in the second
and third lines would be Kg/m. [Kilogram/Metre)
def calc_BMI(weight,height):
bmi = (weight/(height*height))*703.0
print 'Your BMI is : ', BMI 'weight units/height units.' # You need to put
the correct text here.
if bmi <=18.5:
return ' You are underweight.'
if 18.5 <= bmi <= 24.9:
return 'Your weight is in the normal range.'
if 25.0 <= bmi <= 29.9:
return 'You are overweight.'
if bmi >= 30:
return 'You are, I regret, obese.'
I hope that I am halfway correct.
With best wishes,
Sydney
