Creating a new instance of a class by what is sent in?
I am sorry if this is obvious, but I am not seeing it. How would I go about creating a new type that is of the same type as a class sent into the function? new = foo.__init__() refers to the current foo, not a new fresh instance of my class. The only way I can think of is to make a large if-elif chain of isinstances, but that loses the generality I am after. Thank you for your help. -- http://mail.python.org/mailman/listinfo/python-list
Re: numarray.array can be VERY slow
Yes because that is a bad way to things. There is no reason to be working with a list when it could be done directly with numarray. -- http://mail.python.org/mailman/listinfo/python-list

Re: Best editor?
Well I would be more than willing to learn Emacs if it does all these things you speak of, but really I can't get started because the default scheme is so friggin ugly it isn't funny. Anyone want to send me a configuration setup with Python in mind, and decent colors? -- http://mail.python.org/mailman/listinfo/python-list
Best editor?
When not using the interactive prompt, what are you using? I keep hearing everyone say Emacs, but I can't understand it at all. I keep trying to learn and understand why so many seem to like it because I can't understand customization even without going through a hundred menus that might contain the thing I am looking for (or I could go learn another language just to customize!). Personally I like SciTE, it has everything I think a midweight editor should: code folding, proper python support, nice colors out of the box, hotkey access to compile (I'm sure emacs does this, but I couldn't figure out for the life of me how), etc. Opinions on what the best is? Or reading I could get to maybe sway me to Emacs (which has the major advantage of being on everyone's system). -- http://mail.python.org/mailman/listinfo/python-list
Re: Numarray newbie question
Are there no windows binaries for SciPy for python 2.4 yet? I try to run the installer and it complains that it can't find python 2.3. Besides that, vectorize is exactly what i want. -- http://mail.python.org/mailman/listinfo/python-list
Re: Numarray newbie question
Oh well. I am downloading all the things to build it, but in the mean time I just did: def get_y_mat(x_ind,y_ind): return self.y_min + y_ind*self.dy def get_x_mat(x_ind,y_ind): return self.x_min + x_ind*self.dx self.x_mat=fromfunction(get_x_mat,matshape) self.y_mat=fromfunction(get_y_mat,matshape) def fxy(x_ind,y_ind): x=self.x_min + x_ind*self.dx y=self.y_min + y_ind*self.dx return f(x,y) def vxy(x_ind,y_ind): x=self.x_min + x_ind*self.dx y=self.y_min + y_ind*self.dx return v(x,y) self.f_mat=fromfunction(fxy,matshape) self.v_mat=fromfunction(vxy,matshape) As you can see I am just repeating calculations in fxy and vxy that I have already done for x_mat and y_mat. This is still faster than saying: self.f_mat = array([f(x,y) for x in x_mat for y in y_mat],matshape) by a noticable amount. -- http://mail.python.org/mailman/listinfo/python-list
Numarray newbie question
I know there are probably alternatives for this with the standard library, but I think that would kill the speed I get with numarray: Say I have two 2-dimensional numarrays (x_mat and y_mat, say), and a function f(x,y) that I would like to evaluate at every index. Basically I want to be able to say f(x_mat,y_mat) and have it return a numarray with the same shape and element wise evaluation of f. I know, I want a ufunc, but they look scary to write my own. Are there any functions that do this? Or is writing ufuncs easier than it seems? Thanks, -Chris Neff -- http://mail.python.org/mailman/listinfo/python-list
