Introduction of Python Programming – What Is Python?
Introduction of Python programming begins with a simple yet powerful idea: creating a language that anyone can read, understand, and write with ease. Python is a high-level, interpreted, general-purpose programming language designed to prioritize code readability and developer productivity.
Unlike many languages that rely on complex syntax rules, Python uses clean, English-like commands, making it the top choice for beginners and experienced developers alike. Whether you want to build websites, analyze data, create AI models, or automate everyday tasks, Python provides the tools to do it efficiently.
Today, Python consistently ranks as the world’s most popular programming language according to the TIOBE Index and Stack Overflow Developer Survey, and is widely used by global companies like Google, Netflix, Instagram, NASA, and Spotify.
What is Python in simple words?
Python is a programming language that tells computers what to do using simple, human-readable instructions. It can be used to build websites, work with data, create AI, and automate repetitive tasks.
History and Evolution of Python
Understanding the history of Python helps you appreciate why it is built the way it is. Python was created by Guido van Rossum, a Dutch programmer, while he was working at Centrum Wiskunde & Informatica (CWI) in the Netherlands. He began developing Python in the late 1980s as a side project during the Christmas holidays.
Year | Milestone | Significance |
1989 | Python development begins | Guido van Rossum starts writing Python as a hobby project |
1991 | Python 0.9.0 released | First public version — included classes, exception handling, and functions |
1994 | Python 1.0 released | Added lambda, map, filter, and reduce functions |
2000 | Python 2.0 released | Introduced list comprehensions and garbage collection |
2008 | Python 3.0 released | Major redesign — improved Unicode support and fixed design flaws |
2020 | Python 2 end of life | All support shifted to Python 3 |
2023–2026 | Python 3.11–3.13+ | Faster execution, improved error messages, JIT compilation research |
The name “Python” was inspired not by the snake but by the British comedy series Monty Python’s Flying Circus, which Guido van Rossum was a fan of. He wanted the language to feel fun and approachable — a philosophy that continues to define Python’s community today.
Key Features of Python Programming Language
One of the biggest reasons Python is recommended as the first programming language for beginners is its rich set of features that make coding easier, faster, and more enjoyable.
Feature | Description | Real-World Benefit |
Simple and Readable Syntax | Uses English-like commands with minimal symbols | Beginners write working code faster with fewer errors |
Interpreted Language | Code runs line by line without pre-compilation | Easier to test and debug programs instantly |
Dynamically Typed | No need to declare variable data types explicitly | Faster development and more flexible coding |
Object-Oriented | Supports classes, objects, inheritance, and polymorphism | Builds structured, reusable, and scalable software |
Large Standard Library | Built-in modules for file handling, networking, math, and more | Reduces need to write code from scratch |
Cross-Platform | Runs on Windows, macOS, Linux, and Raspberry Pi | Write once, run anywhere without modification |
Extensive Third-Party Libraries | PyPI hosts over 500,000 packages (NumPy, Pandas, TensorFlow, Django) | Accelerates development across all domains |
Open Source and Free | Python is free to download, use, and distribute | No licensing cost — ideal for students and startups |
Strong Community Support | Millions of developers, tutorials, and forums worldwide | Solutions and learning resources are always available |
Embeddable and Extensible | Can be integrated with C, C++, and Java | Adds scripting capability to existing applications |
Basic Python Syntax for Beginners
One of the most exciting parts of the introduction of Python programming is how clean and simple the syntax is. Even someone without a technical background can read a Python program and understand what it does.
Your First Python Program
print("Hello, World!") That single line is a complete Python program. No semicolons. No curly braces. No complex declarations.
Python Variables and Data Assignment
name = "Rahul"
age = 25
city = "Hyderabad"
is_student = True
print(name, "is", age, "years old and lives in", city)
Conditional Statements (if / else)
marks = 85
if marks >= 90:
print("Grade: A+")
elif marks >= 75:
print("Grade: A")
else:
print("Grade: B")
Loops in Python
# For Loop
for i in range(1, 6):
print("Python Step", i)
# While Loop
count = 1
while count <= 3:
print("Count:", count)
count += 1
Functions in Python
def greet(name):
return f"Welcome to Brolly Academy, {name}!"
message = greet("Priya")
print(message)
Notice how Python uses indentation (spaces) instead of curly braces to define code blocks. This forces developers to write clean, consistently formatted code — one of Python’s defining characteristics.
Python Data Types and Variables
Python supports a wide range of built-in data types that allow you to work with numbers, text, collections, and more.
Data Type | Category | Example | Usage |
int | Numeric | age = 22 | Whole numbers and counters |
float | Numeric | price = 99.99 | Decimal values and measurements |
str | Text | name = “Python” | Text, names, messages |
bool | Boolean | is_active = True | True/False conditions |
list | Collection | skills = [“Python”, “SQL”, “ML”] | Ordered, changeable sequences |
tuple | Collection | coordinates = (17.3850, 78.4867) | Ordered, unchangeable data |
dict | Mapping | student = {“name”: “Arjun”, “age”: 21} | Key-value pairs |
set | Collection | unique_cities = {“Hyderabad”, “Pune”, “Bangalore”} | Unique, unordered items |
NoneType | Null | result = None | Represents absence of value |
Object-Oriented Programming in Python
Python fully supports Object-Oriented Programming (OOP), which allows developers to model real-world entities using classes and objects. OOP makes large codebases more organized, reusable, and easier to maintain.
Core OOP Concepts in Python
- Class:A blueprint that defines the structure and behavior of objects.
- Object:A specific instance created from a class.
- Inheritance:A child class inherits properties and methods from a parent class.
- Encapsulation:Bundling data and methods together and restricting direct access.
- Polymorphism:The ability of different classes to share the same method name with different behaviors.
class Student:
def __init__(self, name, course):
self.name = name
self.course = course
def introduce(self):
return f"Hi, I am {self.name} and I am learning {self.course} at Brolly Academy."
student1 = Student("Ananya", "Python Full Stack")
print(student1.introduce())

How Python Works – Step by Step
Understanding how Python works internally helps you write better code and troubleshoot issues more effectively.
- Write the Code:The developer writes Python code in a .py file using a text editor or IDE like VS Code, PyCharm, or Jupyter Notebook.
- Source Code Compilation:Python’s interpreter compiles the source code into an intermediate format called bytecode (.pyc files stored in __pycache__).
- Python Virtual Machine (PVM):The bytecode is sent to the PVM, which is the runtime engine that executes instructions one by one.
- Execution:The PVM translates bytecode into machine-level instructions that the computer’s CPU can understand and execute.
- Output:The result — whether it is printed text, a saved file, a web page, or a trained model — is delivered to the user.
Key Insight: Python uses the CPython interpreter by default (written in C). Other implementations include PyPy (faster), Jython (runs on JVM), and IronPython (runs on .NET).
