I am trying to teach a computer program - to program. It builds grammars
and procedural memories on dictionary networks. How do I get the program
to be able to input to the interpreter/command line and read the
results?
You probably don;t want to do that. I suspect you just want to
execute a string that your program has created? If so you can
use the exec or eval functions in Python.
If you do want to create an interactive prompt for your users you might
like to look at the cmd module which includes the tools for building
a command prompt type environment similar to the pdb debugger.
I have done this a wee bit with making a dictionary of
functions, but in a sense I am creating a script language on top of a
script language so it seems really dumb to me especially since I have to
recreate the grammar.
Not really sure I understand? Are you creating a new grammar or are
you using Python syntax etc but just adding new features/commands?
If the outputr is valid python syntax then you can use exec/eval but if
you are creating your own dialect then you will need to buld a parser
- using any of the excellent python parsing tools available?
