Python 3.15 released with explicit lazy imports and new unpacking syntax
Why it matters for readers: These features change how Python code can be written and may make some programs start faster and look cleaner.
- Python 3.15 adds explicit lazy imports via the new 'lazy import' syntax from PEP 810.1
- Unpacking inside comprehensions is supported, illustrated by new [*sublist for sublist in lists] and similar constructs from PEP 798.1
- The author notes that dropping support for Python 3.10 lets them start using features from newer versions such as 3.11 and 3.15.1
- Explicit lazy imports are expected to reduce startup cost for CLI tools and plugin systems that otherwise import heavy dependencies like sentence_transformers.1
