Python 04 Expert

This level extends the Python track into context management, references, concurrency, performance, and module organization.

Learning Metadata

• Difficulty: Advanced.
• Estimated Time: 4-6 hours across modules, project, and assessment.
• Prerequisites: Completion of 03-advanced plus its project or assessment checkpoint.
• Study Strategy: Finish the modules in order, then the capstone, then the assessment, and explicitly compare runtime, ownership, and scaling tradeoffs across languages.

Module Order

1. memory-management-and-raii
2. smart-pointers-in-depth
3. concurrency-basics
4. performance-and-profiling-basics
5. modularization-and-build-structure

Track progress in ../CHECKLIST.md.

Level Outcomes

• Use context managers and explicit close patterns for predictable cleanup.
• Reason about references, weak references, and ownership-style transfer examples.
• Build concurrent examples with synchronized shared data.
• Measure simple hot paths and organize larger programs across modules and files.

Done When

• You completed every module in this level.
• You solved all exercises (01.py and 02.py) for each module.
• You can explain cleanup, concurrency, and performance tradeoffs.
• You completed project languages/python/projects/04-expert.

Study Tip

Use this level to compare Python's context managers, weak references, threads, and module layout with the expert tracks in C++, Go, and C#.
