Hi just starting to get to grips with writing GUIs in Python using wxPython and not being a computer scientist, have a philosophical question about the "best" way to pass data between various modules. For example, I anticipate having one module to look after the GUI stuff where users can input data (either from the keyboard or file), another to process the data and (probably) a third to display the calculation results. Just not sure what the most efficient way of passing data between the various modules. I can think of 4 ways to do this, of which 1 is not possible in Python (I think).
(1) via temp files: modules read to and write from temporary files (2) via function arguments: data passed from one module to another via argument lists. This seems the most logical but I have an irrational dislike of long argument lists. Could pass data objects (eg. C type structs) or dictionaries via the argument list but I don't think this gets around the "problem" of long argument lists and we now need pack/unpack type functions. Maybe this isn't a problem anyway? (3) via globals: AFAIK this is not recommended so we will move swiftly on (4) indirectly: thinking here of something along the FORTRAN COMMON blocks which (I think) Python doesn't have So, looks like it's a choice between (1) and (2) - or have I missed something obvious? What is the most "pythonic" way of doing this?
