- Python – Dictionaries & Sets
Dictionaries and sets are two of the most powerful and frequently used data structures in Python. Dictionaries give you a fast, flexible way to associate keys with values — think of them as a lookup table where you can instantly retrieve data by its label. Sets give you an unordered collection of…
- Python – Lists & List Comprehensions
Introduction Lists are the workhorse of Python data structures. If you write Python for any length of time, you will use lists more than almost anything else. They are ordered, mutable, and flexible enough to hold any mix of data types. Whether you are storing user records, processing CSV rows,…
- Python – Function
If you have been writing Python for any length of time, you have already been using functions — print(), len(), range(). Functions are the fundamental building blocks of reusable, maintainable code. They allow you to encapsulate a piece of logic, give it a name, and call it whenever you need it,…
- Python – Iteration(for/while loops)
Introduction Iteration is one of the foundational concepts in programming. At its core, iteration means executing a block of code repeatedly — either a fixed number of times or until a condition is met. Without loops, you would have to write the same logic over and over for every element in a…
- Python – Introduction
What is Python? Python is a general-purpose, high-level programming language that has become the default tool for a massive range of software work — from web backends and automation scripts to machine learning pipelines and data analysis. It is open source, cross-platform (runs on Windows, macOS,…
