Lecture 1: Python Fundamentals & Basic Programming Concepts

Welcome to your first lecture in learning Python! In this session, we'll cover the foundational programming concepts you need to get started with Python. We will break down key terms, explore how Python works as an interpreted language, and understand the basic building blocks like syntax, keywords, and indentation that form the core of writing Python programs.

1.1 What is a Program?

A program is a set of instructions written in a programming language that a computer follows to perform a specific task. These tasks can be as simple as printing a message on the screen or as complex as managing data in a database.

• Example: Think of a program like a recipe that tells a chef (the computer) what steps to follow to prepare a meal. Just like in cooking, the instructions must be clear and in the correct order, or else the meal (program) might not turn out as expected.
