There are two main methods for translating high-level programming languages into machine code that computers can understand: interpreters which translate code line-by-line and are better for debugging, and compilers which translate the full program at once for faster execution but make debugging harder through error files instead of line-by-line feedback. High-level languages are written to be easier for humans to understand but must be translated before a computer can execute the code either through an interpreter or compiler.
