This article explains the difference between Python's '/' and '//' operators, showing how '/' performs floating‑point division while '//' carries out integer (floor) division, and provides concise examples to help readers apply the correct operator in their code.
This article walks through seven tricky Python snippets—default mutable arguments, lambda closures, class variable inheritance, division differences between Python 2 and 3, out‑of‑range slicing, list multiplication side effects, selective list comprehensions, and custom dict subclasses—explaining their outputs and how to fix them.
This article walks through several puzzling Python code snippets, explaining why default mutable arguments share state, how closures suffer from late binding, the inheritance of class variables, differences in division between Python 2 and 3, list slicing quirks, and how list multiplication creates shared references, while also offering corrected implementations.
This article explains the major changes introduced in Python 3.0—including the new print() function, unified Unicode strings, altered division behavior, updated exception syntax, removal of xrange, revised literal formats, module renames, and data‑type updates—while offering guidance for migrating existing Python 2 code.
