Is it me or Python memory management? 🤔💻
summary
Explains that every Python value lives on a private heap as an object with fields (value, type, reference count), shows how assignments increment and decrement refcounts, and describes the two-pronged cleanup: immediate reference counting and cyclic garbage collection with configurable thresholds and manual calls like gc.collect. Demonstrates practical diagnostics with memory_profiler, warns that caches and reference cycles create “immortal” objects, and recommends hardware choices (RAM/SSD/CPU) based on workload.
