🔰 Introduction:

In today’s digital world, programming has become almost as essential a skill as reading and writing. It’s not just for programmers; it benefits entrepreneurs, designers, engineers, and even students.
If you’re a complete beginner, don’t worry! In this series, we’ll start step-by-step with Python, a programming language that’s easy to read and understand.

✅ Why Python in particular ?

Easy to learn and read
Python is similar to English, making it ideal for beginners.

Popular and in-demand
Used in artificial intelligence, web development, data analysis, gaming, and more.

Huge and supportive community
Thousands of free lessons and libraries, and ongoing online support

🛠️ Preparing Your Work Environment

1. Download Python

Go to the official website: https://www.python.org/downloads
and download the appropriate version for your system (Windows/macOS/Linux).

✅ Make sure to enable the “Add Python to PATH” option during installation.

2. Open a code editor

The easiest editor for beginners is:

IDLE: It comes with Python.

Or you can use Visual Studio Code:
https://code.visualstudio.com

👨💻 Your First Program: Hello, World !

Open IDLE or VS Code and type the following code:

python
print(“Hello, World!”)

📌 This code simply prints a message to the screen. Congratulations! You’ve created your first program.

📚 Basic Concepts in Python

1. Variables:

python
name = “Ali”
age = 25
name and age are variables.

= means “assign value”.

2. Data Types :

Type Example
String (str) “Ali”
Integer (int) 25
Float (float) 3.14
Bool (bool) True, False

🧪 Simple Exercise :

Write a code that asks for your name and age and then prints a welcome message:

python
name = input(“What is your name?”)
age = input(“How old are you?”)
print(“Hello, ” + name + “! Your age is ” + age + ” years.”)
🟡 Note: input() is used to input data from the user.

🧠 Additional Challenge :

Modify the program to calculate how many years you have left until you reach 100:

python
age = int(input(“How old are you?”))
years_left = 100 – age
print(“You have ” + str(years_left) + “1 year left until you reach 100!”)

📝 Conclusion :

Programming isn’t as difficult as you thought.

Python is a fun and ideal language for beginners.

You learned how to write simple code using print() and input().

📌 What will we learn in Lesson 2?

In the next lesson, we’ll learn more about data types and how to write code with logical interaction using conditional statements.
