Introduction
Memory optimization has become a central concern for Python practitioners in 2025, particularly in domains such as large‑scale data processing, AI pipelines, and web scraping. Python’s ease of use and rich ecosystem come with trade‑offs: a relatively high memory footprint compared to lower‑level languages, and performance overhead from features like automatic memory management and dynamic typing. For production workloads—especially long‑running services and high‑throughput scrapers—systematic memory optimization is no longer an optional refinement but a requirement for stability and cost control.
