You don't know what a Ti 83 is. Calculator. The most basic programming
available. It already has so many functions built into it that it is much
easier to tell it to do things. You don't have to do all this integer
conversion and such whatnot. Wow... I'm really unsure of how this thing is
supposed to work. It seems the more I learn about Python, the more confused I
become. It's enough to bring tears to your eyes. Not really but 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:
