I got this response:
Close, but in most programming languages, the operations go on the right
and the result goes on the left. That means you want
ans =3D a * b
Then all you need to do is print it, like this:
print 'Answer: ' , ans
So I now have this:
#Calculator functions
a =3D raw_input ("First Number:")
b =3D raw_input ("Second Number:")
ans =3D a*b
print 'Answer:', ans
I end up with this:
First Number:8 ( I typed in the 8 )
Second Number:7 ( Ityped in the 7)
Traceback (innermost last):
File "C:\Python20\prog1.py", line 4, in ?
ans =3D a*b
TypeError: can't multiply sequence with non-int
So I am definitly getting warmer just not quite. should I change line =
placement?
Thanks,
Brendhan
