Introduction to Python

What is Python?

Python is a high-level, easy-to-learn, and powerful programming language used in almost every field of technology — from building websites and automating tasks to data analysis and artificial intelligence.

But what makes Python truly special?

It’s the simplicity.

Python is designed to be easy for humans to read and write, even if they’re not professional programmers. That’s why it has become the most popular language for beginners, professionals, and even non-technical people entering tech.

Why is Python So Popular?

Here are a few reasons why Python is everywhere:

Simple and Clean Syntax

Python code looks almost like English. You don’t have to use confusing curly braces ({}) or semicolons (;) like other languages. This makes Python a favorite for people who are just starting out.

("Hello, World!")

This line prints “Hello, World!” — that’s all. Simple, right?

Versatile and Powerful

Python can be used for:

• Web development (Django, Flask)
• Data science & Machine Learning (Pandas, NumPy, scikit-learn)
• Automation & Scripting (automate boring tasks)
• Game development (Pygame)
• App development (using Kivy or PyQt)
• Cybersecurity tools
• And even Artificial Intelligence and Robotics

Huge Community Support

No matter what problem you’re facing, chances are someone has already solved it and shared the solution online. Python has millions of users, thousands of open-source libraries, and an active global community.

Who Uses Python?

Python is used by:

• Beginners who want to learn programming
• Data analysts and data scientists
• Software engineers and web developers
• Teachers and researchers
• Automation engineers
• Even non-programmers like accountants or marketers who want to automate tasks

In short, anyone who works with data or computers can benefit from learning Python.

What Can You Build with Python?

Let’s look at some real-world examples of what you can do with Python:

How Does Python Work?

Python is an interpreted language, which means you don’t need to compile it like C++ or Java. You write the code, run it, and it works immediately.

Python uses .py files and runs them line by line.

You can write Python code in:

• Text editors like Notepad or VS Code
• IDEs like PyCharm or Thonny
• Online platforms like Google Colab or Jupyter Notebooks (great for data science)

Basic Syntax: How Python Looks

Let’s look at a few simple examples.

👉 Print a message

print("Welcome to Python")

print("Welcome to Python")

👉 Variables

name = "Tejas"
age = 25

name = "Tejas"
age = 25

👉 If-Else condition

if age > 18:
    print("You are an adult.")
else:
    print("You are a minor.")

if age > 18:
    print("You are an adult.")
else:
    print("You are a minor.")

👉 Loop

for i in range(5):
    print("Count:", i)

for i in range(5):
    print("Count:", i)

👉 Function

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

greet("Smart Tejas")

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

greet("Smart Tejas")

What You Need to Start Learning Python

To get started, all you need is:

1. A computer or laptop (Windows/Linux/Mac)
2. Python installed (latest version: Python 3.x)
3. A code editor (we recommend VS Code)
4. A curious mind and regular practice

If you don’t want to install anything, you can also use online platforms like:

• Google Colab (especially good for data analysis)
• Replit.com
• Jupyter Notebook (comes with Anaconda)
