help in creating a new language with python

[Ofnuts]

who says that python can only compile a file with .py extension?

Does that mean that  python can also compile filename with( the( .txt) ,( .js ) ,(.c) ,( .class) ,( .jar)  and any other text file extension.)
i dont think so.

Only the actual file contents count.... the file extension is a mere convention. People tend to stick to it because it is useful but it is in no way mandatory.
