Python Dictionary (with Examples)
What is a Python dictionary? A Python dictionary is a built-in mapping type that stores values under keys. It’s implemented with an internal hash table that maps each hashable key to a memory location for its value. Dictionaries are the go-to structure for lookups and mappings in Python. We can think of them as fast… Continue reading Python Dictionary (with Examples)
Python List (with Examples)
Introduction to Python Lists Python lists are versatile data structures that allow you to store and manipulate collections of items. A list is an ordered collection of elements enclosed in square brackets []. Each item in a list is separated by a comma. Lists are mutable, meaning their elements can be modified after creation. Python List… Continue reading Python List (with Examples)
Queue in Python
A Queue in Python is a linear data structure that follows the FIFO (First In, First Out) principle — meaning the first element added is the first one removed. Queues are widely used in task scheduling, data buffering, and asynchronous programming (like producer-consumer models). Front → [A, B, C, D] → Rear Enqueue(E) → [A,… Continue reading Queue in Python
How to Limit Heap Size in Python?
In Python, memory management (including heap allocation) is handled automatically by the Python Memory Manager and Garbage Collector (GC). Unlike low-level languages such as C or C++, Python does not expose direct APIs to manually set or cap heap size. However, if you’re running applications in restricted environments (like containers, servers, or embedded systems), or… Continue reading How to Limit Heap Size in Python?
