This article explains the purpose and typical usage of various Python file extensions—including .py, .ipynb, .pyi, .pyc, .pyw, and .pyx—provides code examples, demonstrates how to write type‑hint files, and compares pure Python with Cython for performance‑critical tasks.
This article explains why JPEG and JPG are interchangeable, tracing the JPEG format’s 1992 origins, early Windows 8.3 filename constraints that led to the .jpg shortcut, and how modern operating systems have lifted the historic 260‑character path length limit, affecting developers with deep file hierarchies.
This article introduces the most common Python file extensions—including .py, .ipynb, .pyi, .pyc, .pyd, .pyw, and .pyx—explains their purposes, provides example code, and demonstrates how Cython (.pyx) can significantly improve performance for compute‑intensive tasks.
This article explains the most common Python file extensions—including .py, .ipynb, .pyi, .pyc, .pyd, .pyw, and .pyx—describes their purposes, shows example code for each, and demonstrates how Cython can dramatically improve performance for computation‑intensive tasks.
Microsoft’s recent Windows 10 updates let Explorer create and rename files that consist solely of an extension, a change that benefits web developers and users needing dot‑prefixed files, and the article explains how to enable this feature, workarounds for older versions, and command‑line methods.
