aroyalprince/Lodu-Code ? reverse-engineered prompt

Build me a small desi style programming language called Lodu Code, with a simple Python based interpreter so I can run .lodu files from the command line.

It should support basic things like variables, numbers, strings, math, if else, loops, functions, and a few simple data types. I want the sample .lodu programs in the repo to actually work, like the calculator, datatype, first, func, ifelse, loops, and similar examples.

Please make it feel easy to use, with clear error messages when something goes wrong, and a simple way to run a script after installing it. If anything is unclear, look up current docs online if you need to and then build the most practical version of it.
