What is Python? Python is a high-level, general-purpose, interpreted programming language known for its emphasis on code readability. These Python interview questions cover lists, generators, memory management, and OOP.
Lists are mutable data structures defined with square brackets `[]`, allowing item additions or updates. Tuples are immutable sequences declared with parentheses `()`, meaning their items cannot be modified after declaration.
Generators are functions returning lazy-evaluating iterators using the `yield` statement. Unlike lists, they do not load the entire sequence into RAM, making them ideal for processing massive data streams and files efficiently.
Python manages memory automatically using a private heap memory layout. It relies on reference counting to track object instances and a built-in garbage collector to resolve reference cycles and free up unused memory.
