ya.Someone else helped me with the problem of accepting numbers and words. I
used:if shape in["1","circle"]:something like that. It works wonderfully. I'm
not sure why, but I know that it does and that is enough. Someone else also
said that I had to convert to int, and I did. That was
another problem, which is now fixed.But, as usual, it is just one problem after
another. Now I have run into this error message: Traceback (most recent call
last): File "C:\Documents and Settings\HP_Owner\Python0\area.py", line 23, in
<module> area = 3.14*(radius**2)TypeError: unsupported operand type(s) for
** or pow(): 'str' and 'int'>>> and others like
this:Traceback (most recent call last): File "C:\Documents and
Settings\HP_Owner\Python0\area.py", line 19, in <module> area =
height*widthTypeError: can't multiply sequence by non-int of type 'str'>>> Very
frustrating. What is a non-int and what is 'str'? Why can't it multiply the
sequence? I guess I should include the program I'm using for these things.I'm
having this problem with both of these attached. The messages above are from
area.py. area.py is sort of a prototype of radiacir.py, a test version. You
know, I should probably try that int trick, which I seem to have forgotten.
And guess what that did it. It's amazing when you apply the things that you
learn. Apparently I am quite absent minded. Well It seems
I don't need any of this help anymore. Oh well. Thanks anyway.Au > To:

Do you really think someone can or will read what you wrote? I've
never seen something so horribly formatted like you emails - and I've
seen lots of awful formatted emails...
