dir()function to explore module contents - The difference between module attributes and functions
The author includes several hands-on examples that demonstrate how to import and use existing modules, making the concept concrete for beginners.
Chapter 3: Creating Your Own Modules
Building on the foundation of understanding modules, this chapter guides readers through creating their own modules from scratch. Key topics include:
- Organizing related functions into cohesive modules
- Best practices for module naming and structure
- Creating module documentation with docstrings
- The
if __name__ == "__main__":pattern explained - Module-level variables and their scope
This chapter includes practical exercises where readers create and import their own custom modules, reinforcing the concepts through active learning.
Chapter 4: Exploring the Python Standard Library
One of the book's most valuable sections is the guided tour through Python's rich standard library. Dargslan expertly curates this vast resource, highlighting:
- Essential built-in modules every Python developer should know
- Time-saving utilities in the standard library
- File handling modules for various formats
- Data structure and algorithm modules
- System and OS interaction modules
Each module description includes practical code examples that demonstrate real-world applications, showing readers how to leverage these tools in their own projects.
Chapter 5: Understanding Python Packages
This pivotal chapter elevates the discussion from single modules to packages - collections of modules that provide more complex functionality. Readers learn:
- The structural difference between modules and packages
- How to create a package with the
__init__.pyfile - The role of subpackages in organizing larger codebases
- Namespace packages introduced in Python 3.3
- Package documentation best practices
Through a step-by-step example of building a multi-module package, readers gain hands-on experience with package creation and organization.
Chapter 6: Absolute vs. Relative Imports
Import statements are a frequent source of confusion for Python developers, but this chapter provides much-needed clarity:
- The syntax and semantics of different import styles
- When to use absolute vs. relative imports
- The implications of PEP 328 on import statements
- Common pitfalls and how to avoid them
- Best practices for maintainable import statements
The author uses visualizations and concrete examples to illustrate these concepts, making a potentially confusing topic accessible.
Chapter 7: Structuring a Real Python Project
Theory meets practice in this chapter as readers learn to apply modular principles to actual project structures:
- Industry-standard project layouts explained
- The importance of separation of concerns
- Configuration management in modular projects
- Managing project dependencies effectively
- Testing strategies for modular code
This chapter includes a complete project example that ties together all the previous concepts, showing how modules and packages work together in a cohesive application.
Chapter 8: Installing and Using Third-Party Packages
No modern Python development happens in isolation, and this chapter expertly guides readers through the ecosystem of third-party packages:
- Using pip and virtual environments
- Understanding package specifications and version constraints
- Reading package documentation effectively
- Evaluating package quality and community support
- Managing dependencies in production environments
The practical examples demonstrate installing and utilizing popular packages, introducing readers to the broader Python ecosystem.
Chapter 9: Publishing Your Own Package to PyPI
For developers ready to contribute back to the community, this chapter covers the process of publishing packages:
- Preparing package metadata with setup.py
- Creating distribution packages
- Uploading to PyPI (Python Package Index)
- Package versioning best practices
- Maintaining packages over time
The step-by-step guide takes readers through the entire publishing process, demystifying what can often seem like a complex procedure.
Chapter 10: Practice Projects
The final chapter solidifies learning through three comprehensive projects that exercise all the concepts covered:
- Building a command-line utility with modular design
- Creating a reusable library package
- Developing a web application with clean architecture
Each project includes requirements, structure guidance, implementation tips, and extension challenges, providing a practical capstone to the learning journey.
Appendices: Quick Reference Resources
The book's appendices serve as valuable reference materials:
- Module vs Package: A clear comparison chart for quick reference
- Template Project Folder Structure: Ready-to-use templates for different project types
