Two Upgrades that will Make Python a Tad Bit More Efficient

Python is beloved for its simplicity and readability, but when it comes to performance, it has some well-known bottlenecks.

Unlike compiled languages like C++ or Java, Python is an interpreted language. This means the code is executed line by line at runtime, which makes development easier but slows execution speed.

Another major limitation is the Global Interpreter Lock (GIL), which prevents multiple threads from running Python bytecode simultaneously. This restriction makes it hard to take full advantage of modern multi-core CPUs. Additionally, Python’s dynamic typing system — where variable types are determined at runtime — adds further overhead due to frequent type checks and conversions[1].

And while automatic memory management through garbage collection makes development smoother, it introduces inefficiencies that impact performance in memory-intensive applications[2].

But Python isn’t standing still. Version 3.14 is packed with optimizations to make Python faster and more efficient. This article explores two game-changing upgrades: the new annotationlib module and a CPython tail call interpreter— which promise to improve execution speed without compromising Python’s ease of use.

Python 3.14 introduces the annotationlib module, which provides tools for inspecting annotations on modules, classes, and functions. Annotations… Read the full blog for free on Medium.
