This is not a compiler that does python -> llvm. It is a way to build llvm IR from python using the C++ API. Otherwise you output LLVM IR as text, and call the llvm command line tools to do stuff with it.
For example, you can use this to generate LLVM IR at runtime, and use the LLVM JIT to compile and execute that LLVM code.
