Well, I'm trying to create an interactive program, let's say I'm running the program, I ask the user to give the array a name, I then do some computations and store the results in that array. While I'm still running the program I might decide to create several more arrays of the same type/dimension with names of my choosing same types of computation. When I'm done, I might have several arrays created, all with different names that I have given them. In the ipython mode I could call up any of these arrays off and on again as I want to visually compare them to each other. I mean I guess what I could do is go back to my code, name the array Chris, let a calculation use x=2, save, run the program, go back in to the code, edit it so that the array is named Bob along with changing x=3, save, run the program a second time. When I'm done I'll now have two arrays, one named Chris the other Bob with different results because I changed some other input paramenters. I just now thought of maybe making one huge array, storing all the results of x=2 and use a conditional satement like if x=2, then name was Chris. But it would be so much easier if I could type print Chris or print Bob and it woulds spit out what those arrays were. > From: roadier...@googlemail.com > Date: Wed, 15 Jul 2009 16:33:00 +0100 > Subject: Re: [Tutor] objects becoming pointers > To: cjhyne...@hotmail.com > CC: tutor@python.org > > 2009/7/15 chris Hynes <cjhyne...@hotmail.com>: > > I guess I have to start somewhere to ask............ > > > > I want the user to input a name, say "Chris".
