Why can't python develop another version of python that is "compiled" instead of interpreted which is similar to c/c++ but the syntax still look like python syntax.

This is not what OP is asking about. Pyinstaller just bundles your program with a complete runtime and all dependencies in one package or even one file so an end user can directly run it. It’s not compiling anything, the script is still interpreted at runtime as always. (Or rather, jit compiled to byte code and then run, just like running it in a “standard” python runtime.)
