A collection of study notes from my university and self-learning journey. This series covers Python fundamentals step by step — from setup to core concepts — to help both myself and others build a solid foundation in coding.
I upload these materials primarily for my own self-study. Still, I hope they might be helpful to someone else as well. Day 1 — Python Setup & Basic Functions (print, type) 01. Setting up the Environment Install Python (version 3.10+ recommended) In...
01. What is a Variable? A variable is like a label that stores data. Use the = operator to assign a value. x = 10 # Integer (int) y = 3.14 # Floating-point number (float) name = "Sabin" # String (str) is_ok = True # Boolean (b...
Day 3 — Operators in Python 01. Arithmetic Operators Operator Meaning Example Result + Addition 5 + 2 7 - Subtraction 5 - 2 3 * Multiplication 5 * 2 10 / Division (float) 5 / 2 2.5 // Floor division 5 // 2 2 % Modulus (remainder) 5 % 2 1 ** Exponenti...
Day 4 — Input & Output in Python 01. Output with print() The print() function displays values on the screen.When printing multiple values separated by commas, Python automatically adds spaces. print("Hello") print("Age:", 25, "years") # Output: Age...
1️⃣ Basic if Statement Code inside the block runs only if the condition is True. age = 20 if age >= 18: print("You are an adult.") # Condition is True → executed ⚠️ Note: Indentation matters! In Python, 4 spaces are recommended. 2️⃣ if ~ e...
Day 6 – Loops (for / range) 01. What is a Loop? Loops are used when you want to repeat the same action multiple times.In Python, the two main types of loops are for and while.(Today we focus on for loops.) 02. Basic for Loop A for loop iterates over...
