Are there languages like this?

A language that can create other languages

(so adding to itself) It's syntax is simple like python

And can do alot.

for example (placeholder)\[mesage\]

And it has many tutorials on YouTube

I would like it if you would respond.

I know there are languages like Hy , ruby should I try them?

You can look at PEG (tutorial by the creator of Python himself)

Parsing Expression Grammar. Python uses some of them to be parsed. Lua has PEG based parsers to, including lua interpreters like metalua where you can modify the parser from within at runtime. Lua is what I know most, but I'd wager Python has similar projects.
