IS PYTHON CODE SENSITIVE TO CPU CACHING?

Summary from the TLDR Web Dev newsletter

CPU caching affects Python code performance despite Python's high-level nature. Experiments comparing sequential and random list access show that random access is significantly slower, especially with larger lists exceeding cache sizes. This means that cache-aware programming is relevant even in interpreted environments like CPython.
