Ajay7616/ThalapathyVJ_Programming_Language ? reverse-engineered prompt

Build me a small custom programming language in Python called ThalapathyVJ, with a simple interpreter that can run files ending in .tvj.

I want the language to support basic print output, variables, numbers, strings, booleans, math, comparisons, logic, bitwise operations, and a few fun string helper commands like uppercase, lowercase, replace, split, join, and find index. The syntax should use the Vijay themed keywords from the README, so it feels like a fan made language, not plain Python.

Please make it so I can write a .tvj file, run it from the command line, and see the output in the terminal. Include a few example programs for printing, a calculator, and string manipulation, and make sure the lexer, parser, and interpreter work together cleanly.

If you need to check anything, look up current docs online if that helps.
