Exception handling should be explicit and granular . Catching bare except: hides KeyboardInterrupt and system exits. Advanced code defines custom exception hierarchies and uses else (run if no exception) and finally (cleanup) purposefully. Advanced code defines custom exception hierarchies and uses
The first step toward advanced Python is embracing functions as first-class objects. exemplify metaprogramming—allowing developers to modify or enhance functions without permanently altering their source code. A decorator like @lru_cache transforms a recursive Fibonacci function from exponential to linear time complexity with a single line. This is not magic; it is a closure that wraps a function with stateful behavior.
