Introduction: Python's Popularity and the Need for Critical Evaluation Python’s meteoric rise as the go-to language for data science, machine learning, and web development is undeniable. Its interpreted nature and dynamic typing make it accessible to beginners, as evidenced by my own journey from the syntactic hurdles of C++ and Java to Python’s intuitive design. However, this very accessibility masks mechanical trade-offs that become critical in performance-sensitive environments. Python’s interpreter executes code line-by-line, introducing overhead that compiled languages like C++ avoid by translating code directly into machine instructions. This overhead is negligible for small scripts but accumulates in CPU-bound tasks, where every cycle counts. The language’s Global Interpreter Lock (GIL) further complicates its performance profile. The GIL is a mutex that prevents multiple native threads from executing Python bytecode simultaneously, even on multi-core systems. While it simplifie
