[Tutor] trouble with "if"

[adam urbas]

Sorry, I don't think Hotmail has turn off HTML.  If it does I havn't been able to find it.  I think you're going to have to explain your little bit of text stuff down there at the bottom.  I have no idea what most of that means.  All my choice things are working now though.  I think that is what you were trying to help me with.  What I used wasif shape in["1","circle"]:and if shape == "1" or shape =="circle":It works perfectly fine now.Ya that little bit o' code is really puzzling.  I wish I knew more about this python deal.  I understand the concept, but not the rules or the techniques and things of that sort.  OK... I've got it... the data=raw_input('Feed Me!').  Ok I now understand that bit.  Then it says Feed Me!  and you put 42 (the ultimate answer to life the universe, everything).  OK, it won't accept the <type 'str'> bit.  it doesn't like the "<".  Well, I just removed that bit and it said:Feed Me!  and I put 42, and it said >>> (I guess it's satisfied now, with the whole feeding).  Well if I understood what 'str' meant, then I could probably figure the rest out.  Well I have to go do other things so I'll save the rest of this figuring out till later.I shall return,Adam> Date: Wed, 23 May 2007 12:12:16 -0400> From: broek at cc.umanitoba.ca> To: adamurbas at hotmail.com> CC: tutor at python.org> Subject: Re: [Tutor] trouble with "if"> > adam urbas said unto the world upon 05/23/2007 11:57 AM:> > > > Hi all,> > > > I've been working with this new program that I wrote.
