  Awesome.

Uh, right. I had a question.
I'm writing a program in Python and am trying to make some kind of thing that allows for scripted objects. However, as I have little to no knowledge of how to write an interpreter beyond the most basic, I decided it would be easiest if I went ahead and made my scripted objects written in Python, as .py files.

However I'm having difficulty finding a way to pop one open and run it. Note I'd much prefer to do this on-the-fly, only for objects I need, so I'm not much for importing.

It would also help if you could tell me how to open files in subfolders; I can only kind of get it working and not in a very pretty way ._.


Thank you for reading, I'd appreciate even a modicum of help although I'm still going to be slowly working this out on my own

Check the eval function, for running a string as python line, and import statement for running a module and making it's symbols available. IIRC, using __import__ function instead of import statement let's you specify the exact location, or you can just add the subdirectory to sys.path.

The open function works fine on subdirectories, so I cannot see what that's about.

eval: my goodness, I'll have to take a deeper look into it though currently it's just handing me errors.

Also, thank you. For some reason I could not fathom that the open function would allow me to add subdirectories before the filename I'm supposed to use os.path or whatever to keep it multiplatformfriendly, right?

Yeah.

Also, if you are using a program like py2exe to pack up your program, but you still want there to be user-editable scripts that are loaded at runtime, there is a neat trick you can do:

Code:

import imp, os
imp.load_source('settings', os.path.join('.','settings.cfg'))
import settings

It will load settings.cfg at runtime (notice how it doesn't even have to be a .py file). I bet you can tell I use this to load configuration / settings files, rather than make up my own config language, use XML, or whatever else.

[Droqen]

Ooooh.
That's interesting. Thanks for the trick, I'll give it a try sometime!

little edit : am continuing to work on stuff, don't hesitate to toss me more ideas if you have any for user-editable scripts... or just ways for ME to have an easier time since I'm lazy :D
