This might seem as silly question but I am thinking there might be the simple solution for this problem. I have a python script which does some mathematical calculation which is command-line-based. I don't want to make any major modification to the code which I have right now. What should be my approach now to create a GUI ( I use wxpython) which uses that script as its model while leaving model to function as stand-alone python script as it is right now. I know it is the question of inheritance and polymorphism but I am not clear about the approach I should take. Any guidelines will be greatly appreciated.
Let's say your command line executable is:
% compute -flag1 -flag2 datafile outputfile
In WxPython you could use check boxes to choose whether flag1 and/or flag2 are used, a file chooser widget for datafile, a text input field for outputfile and 'execute' button. When execute is clicked create a command line in a string and pass it to one of the methods in the subprocess module.
