Complete Phase 7 with imports modules and packages

[RamonRDR]

Summary

• complete Phase 7: Errors, Files, and Modules with Chapter 05, Organizing Code with Imports, Modules, and Packages, in English, Brazilian Portuguese, and Spanish
• teach module objects and import forms, qualified access, aliases, import-time execution, sys.modules, __name__, the main guard, and beginner-level import search context
• teach regular packages with __init__.py while explicitly distinguishing namespace packages
• cover package-level APIs, absolute and relative imports, direct file execution versus python -m, package __main__.py, module-name collisions, wildcard imports, and circular dependency design
• distinguish import packages from installable distribution packages
• add four deterministic executable examples plus small supporting modules/package files
• mark Phase 7 complete across the root status pages, master learning paths, roadmaps, section indexes, project-structure documents, and approved example manifest
• set Phase 8: Standard Library as the next planned learning phase

Validation

• EN / PT-BR / ES chapter structure aligned
• 43 fenced Python blocks identical across all three chapter versions and syntax-checked with ast.parse
• 4 new executable examples, raising the approved manifest from 116 to 120 examples
• repository unit tests passed
• all 120 approved examples passed
• internal Markdown links passed
• repository structure validation passed
• git diff --check and Python compilation passed
• exactly 26 changed files
• one focused commit based exactly on main at 17d83554112e4186d4dc0f78ee03bfac38499b63

References

The chapter is grounded in the official Python 3.14 tutorial and language documentation for modules, packages, the import system, the import statement, __main__, and command-line -m execution.
