*🐍 Python Programming A–Z: Key Concepts You Should Know* *A – Argument* Values passed into functions; can be positional or keyword-based. *B – Boolean* Data type that represents `True` or `False`. *C – Class* Blueprint for creating objects with attributes and methods. *D – Dictionary* Key-value data structure: `{"name": "Alice"}`. *E – Exception Handling* Using `try-except` to manage errors gracefully. *F – For Loop* Iterates over sequences like lists, strings, ranges. *G – Global Variable* Variable declared outside all functions, accessible globally. *H – Heap Memory* Where objects and data structures are stored dynamically. *I – If Statement* Used for decision-making: `if`, `elif`, `else`. *J – Join Method* Combines strings in lists: `' '.join(list)`. *K – Keyword* Reserved words like `def`, `return`, `class`, etc. *L – List* Mutable collection of items: `[1, 2, 3]`. *M – Module* A Python file you can import to reuse code. *N – None* Represents null/empty value in Python. *O – Object-Oriented Programming (OOP)* Supports classes, objects, inheritance, encapsulation. *P – Pass Statement* Used as a placeholder when code is syntactically required. *Q – Queue* FIFO structure implemented using `collections.deque`. *R – Recursion* A function calling itself to solve problems. *S – Set* Unordered collection of unique elements. *T – Tuple* Immutable sequence: `(1, 2, 3)`. *U – Unpacking* Extract values from lists/tuples: `a, b = [1, 2]`. *V – Virtual Environment* Isolates Python projects and dependencies. *W – While Loop* Executes a block while a condition is true. *X – XML Parsing* Handled using libraries like `xml.etree.ElementTree`. *Y – Yield* Used in generators to return values without stopping the function. *Z – Zip Function* Combines multiple iterables: `zip(list1, list2)`.
