Making your own statements

Question

Is there a way to define new statements like def, with, for of my own in Python? Of course, I don't mean to override the existing statements, only create some of my own.

If so, how do I do it? Can you point me to good docs on the subject?

Answer 1

No, you cannot add new syntax within a Python program. The only way to alter the language is to edit and recompile the grammar file and supporting C code, to obtain a new altered interpreter, compiler and runtime.

Answer 2

You can't (re)define language keywords without rewriting a compiler/interpreter/etc. What you could do perhaps is write a something like a DSL (domain-specific language) and something that translates your keyword statements into proper python statements, which might be an easier route.
