The unified_planning library makes it easy to formulate planning problems and to invoke automated planners.
- Define problems in a simple, intuitive, and planner independent way
- Solve your planning problems using one of the native solvers, or by using any PDDL planner
- Dump your problems in PDDL (or ANML) format
- Parse PDDL problem formulations
- Simplification, grounding, removal of conditional effects and many other transformations are available
- and more...

More complex examples are available as notebooks here.
