## AI interpretation — verify before relying

bytecode generates and modifies Python bytecode objects, allowing programmatic creation of executable code from low-level instruction sequences.

Verdict: bytecode is a well-maintained, low-friction library for bytecode generation with permissive licensing and no known vulnerabilities. It is suitable for projects requiring programmatic code generation at the bytecode level, though adoption should account for its Python 3.11+ requirement.
