compile_to_executable()
The very first thing you’ll most likely discover is the block on the backside. The compile_to_executable() operate is strictly what it appears like. Name it, and the present module is compiled to an executable of the identical identify, with all of the @compile-decorated capabilities included.
One other distinction is that the foremost() operate now has the identical signature because the foremost() operate in a C program. This implies the compiled executable will mechanically use that as its entry level.
Lastly, whenever you run this program, the generated executable (which reveals up in a construct subdirectory) doesn’t run mechanically; you need to run it your self. The purpose right here is to construct a standalone C program, indistinguishable from one you wrote by hand in C, however utilizing Python’s syntax.
