Python decorators are an elegant way to wrap functionality around functions or classes (e.g., logging, authorization, caching).
Robust applications do not rely on generic except Exception blocks. High-impact development strategies require defining custom exception hierarchies that mirror your application domain.
Python dominates modern software development due to its readability and massive ecosystem. Writing truly scalable, maintainable Python requires moving beyond basic syntax. You must master advanced design patterns, modern language features, and production-grade development strategies. 1. Advanced Structural Pattern Matching Python decorators are an elegant way to wrap
| Library | Use Case | Key Feature | |---------|----------|--------------| | pypdf (formerly PyPDF2) | Reading, merging, splitting, rotating, cropping | Pure Python, no dependencies | | pdfplumber | Extract text, tables, metadata | Handles complex layouts better | | reportlab | Generate PDFs from scratch | Canvas, Platypus for flowables | | pikepdf | Advanced manipulation, repair, linearization | Wrapper around QPDF | | borb | Modern PDF reading/writing, annotations, forms | OO design, type hints | | pdf2image + pytesseract | OCR on scanned PDFs | Converts pages to images |

Using ExitStack or custom asynchronous context managers guarantees that database connections, network sockets, and file handles are safely closed even if critical exceptions occur mid-execution. 3. Dependency Injection with Protocols The : fail fast with pymupdf
: key: val for key, val in mapping These are not only easier to read but are implemented in C under the hood, making them faster than standard iterative appends. Magic Methods
7. Event-Driven Architecture with Publishers and Subscribers
For tabular data, use camelot-py or tabula-py as a third pass. The : fail fast with pymupdf, refine with pdfplumber only on problem pages.
