1. What is Python?

Python is a high-level, interpreted, and general-purpose programming language known for its simplicity and readability. Guido van Rossum first introduced Python in 1991, and since then, it has evolved into a powerful language used in various domains such as web development, data analysis, artificial intelligence, automation, and more.

2. Why Choose Python for Beginners?

Python’s popularity among beginners can be attributed to its straightforward syntax and ease of learning. The language emphasizes code readability, reducing the cost of program maintenance and development. Additionally, Python has a large and supportive community, providing ample learning resources for newcomers.

3. Installing Python on Your System | Python install

Before you start coding in Python, you need to install it on your computer. The installation process varies slightly depending on your operating system.

3.1 Windows | Python install

To install Python on Windows, follow these steps:

1. Visit the official Python website at
2. Navigate to the Downloads section and choose the latest stable version of Python.
3. Download the installer.
4. Run the installer, and during the installation process, make sure to check the option “Add Python x.x to PATH.”

3.2 macOS | Python install

For macOS users, Python comes pre-installed with the system. However, it’s recommended to install the latest version using Homebrew or the official website.

1. Open the Terminal.
2. Install Homebrew (if not installed) by following the instructions on
3. Run `brew install python`.

3.3 Linux | Python install

Most Linux distributions come with Python pre-installed. To install Python on Linux:

1. Open the Terminal.
2. Update the package list: `sudo apt update` (for Ubuntu/Debian) or `sudo yum update` (for Fedora/RHEL).
3. Install Python: `sudo apt install python3` (for Python 3) or `sudo apt install python` (for Python 2, which is now deprecated).

4. Setting up a Development Environment | Python install

Once Python is installed, it’s essential to set up a development environment to write and execute your Python code. Two popular options are IDLE and Visual Studio Code (VSCode).

4.1 Using IDLE

IDLE is Python’s Integrated Development and Learning Environment, perfect for beginners.

1. Open IDLE from the Start menu (Windows) or using the terminal (macOS/Linux).
2. A new window will open, and you can start writing Python code in the editor.

4.2 Using Visual Studio Code (VSCode)

VSCode is a lightweight yet powerful code editor that supports Python and numerous other programming languages.

1. Download and install VSCode from
2. Install the Python extension for VSCode to enable Python support.
3. Open VSCode, and you are ready to write your Python code.

python install

5. Writing Your First Python Program

Now that you have Python installed and a development environment set up, let’s write your first Python program.

print("Hello, Python!")

6. Understanding the Code

In the above program, we use the built-in `print()` function to display the message “Hello, Python!” on the screen.

7. Running the Program

To run the Python program, follow these steps:

1. Save the program with a `.py` extension, for example, ``.
2. Open your terminal or command prompt.
3. Navigate to the directory where you saved the program.
4. Type `python` and press Enter.

You will see the output: `Hello, Python!`

8. Common Python Terminologies for Beginners

Before we proceed further, let’s familiarize ourselves with some common Python terminologies:

Interpreter: Python is an interpreted language, meaning the code is executed line by line.

– Syntax: The set of rules governing the structure of Python code.

– Variables: Containers for storing data values.

– Data Types:  The classification of data items, such as integers, strings, lists, etc.

– Conditional Statements: Code blocks executed based on specific conditions.

– Loops: Repeated execution of code based on specific conditions.

– Functions: Blocks of reusable code that perform specific tasks.

9. Variables and Data Types

In Python, you don’t need to declare the data type explicitly. The interpreter dynamically assigns data types based on the value assigned to a variable.

9.1 Examples:

# Integer
age = 25

# Float
pi = 3.14

# String
name = "John Doe"

# Boolean
is_student = True

10. Conditional Statements

Conditional statements allow us to make decisions in our code. The common ones are `if`, `elif`, and `else`.

10.1 Example:

age = 20

if age < 18:
print("You are a minor.")
elif age >= 18 and age < 65:
print("You are an adult.")
print("You are a senior citizen.")

11. Loops

Loops help in executing a block of code repeatedly based on a condition.

11.1 Example:

# While loop
count = 1
while count <= 5:
print("Count:", count)
count += 1

# For loop
fruits = ["apple", "banana", "cherry"]
for fruit in fruits:

## **12. Functions**

Functions are reusable blocks of code that perform specific tasks.

12.1 Example:

def greet(name):
print("Hello, " + name + "!")


13. Lists, Tuples, and Dictionaries

Python provides several data structures, including lists, tuples, and dictionaries.

13.1 Examples:

# List
fruits = ["apple", "banana", "cherry"]

# Tuple
point = (10, 20)

# Dictionary
person = {"name": "John", "age": 25, "is_student": True}

14. Python Standard Library

Python comes with a rich set of libraries that extend its functionality. The standard library contains modules for various purposes.

15. How to Keep Learning Python

Python’s versatility and applications are vast. To keep learning and improving your Python skills:

– Join online communities like StackOverflow and Reddit to ask questions and engage with Python enthusiasts.
– Participate in Python-related forums and discussions.
– Take online courses or enroll in coding boot camps that focus on Python.
– Read books and blogs about Python programming.
– Practice regularly and work on small projects to reinforce your understanding.
