I think you shouldn't write text based menus either. You should just write a library of Python functions. To use your software you call these functions from the Python prompt. IPython, an extension for the standard Python interpreter, is good for it. You then work with Python similar to Matlab. http://ipython.scipy.org/moin/ Only when the functions work, then you start to write more simple user interfaces. Your mail illustrates my point: You currently think about user interface stuff and not about the real problem, analyzing spectra of stars. A session with your software would then look like this: ~> ipython In [1]: from analyze_spectra import * In [2]: im1 = load_image("astro/spectra/13-10-2009/im1.fits") In [3]: display_image(im1) In [4]: im1rot = rotate_image(im1, 20, degrees=True) .... And so on. This is much more flexible than Graphical or menu driven user interfaces, and it is much more comfortable for software development. You can write test scripts, instead of clicking around in your unfinished user interface. The added flexibility lets you do odd tasks, that a GUI can't do. And you get automation if you have many similar images for free. If you have Windows users, they can install Python XY. This is a Package that contains a Python interpreter and many libraries for scientists. It contains the libraries that I have recommended, but unfortunately not Pyfits. It also contains Eclipse as a development environment. (I think it is even better than any repository for Suse Linux.) http://www.pythonxy.com/foreword.php Kind regards, Eike. _______________________________________________ Tutor maillist - Tutor@python.org To unsubscribe or change subscription options: http://mail.python.org/mailman/listinfo/tutor
