Python Programming Bootcamp: Build Real World Projects

Hello everyone, and welcome to the first lesson of Section 1 of the Python Programming Bootcamp. In this lesson I will give you a bird’s eye view of the course. The course is divided into 10 sections, and I am listing them for your reference:

SECTION 1 — Introduction to Python

SECTION 2 — Variables, Data Types & Operators

SECTION 3 — Control Flow (If-Else, Loops)

SECTION 4 — Data Structures

SECTION 5 — Functions & Modular Programming

SECTION 6 — File Handling

SECTION 7 — Error & Exception Handling

SECTION 8 — Object-Oriented Programming (OOP)

SECTION 9 — Working with Libraries

SECTION 10 — Real-World Python Projects (Capstone Section)

In this lesson, I will guide you how to install Python on your system.

Now that Python is installed, let’s write our first program.

Python is an interpreted language.
That means Python reads your code line by line and executes it immediately.

Unlike languages such as C or C++, Python doesn’t need a separate compilation step.

I will explain the interactive and script modes of Python.

Python works with several code editors. Let me quickly introduce the most popular ones and focus on VS Code.

In this lesson let’s learn how to take input from a user and display output. We will use VS Code to write and execute our program.

Comments are notes you write inside your code to explain what you’re doing. Lets understand how to use them.

Welcome back!
In this lesson, we’re going to understand one of the most basic, but most important concepts in programming — variables.

In this LESSON, let’s talk about data types — the kind of data Python stores.

Sometimes, you need to convert one data type into another.
This is called type conversion or type casting. Lets learn about this concept in this lesson.

Now let’s look at arithmetic operators, which help you perform mathematical calculations.

In this LESSON, we’ll learn relational and logical operators — essential for decision-making in code.

String formatting allows you to combine text with variables easily. Let learn the modern concept of f-strings.

Let’s build a small project using whatever you’ve learned so far — a Bill Calculator.

Welcome back!

So far, we’ve written programs that run straight from top to bottom. But real programs need decisions and loops. Lets understand these concepts

Let us understand the concept of conditions in Python using if, elif, and else.

Loops save time, reduce errors, and make programs efficient.

Let’s learn them step by step.

Let’s build a useful project — a Password Strength Checker.

Our goal is to check if a password is:

• At least 8 characters

• Contains letters

• Contains digits

• Contains special characters

Welcome to Section 4 of the course!

Python is powerful largely because of its built-in data structures. You will learn about lists, tuples, dicionaries and sets.

A List in Python is an ordered collection of items.

It can store anything: numbers, strings, even other lists. Let's see lists in action.

Let's learn about Tuples which are similar to lists but immutable, which means their values cannot be changed after creation.

In this Lesson I will teach Dictionaries which are one of the most powerful features of Python.

They store data in key–value pairs.

In this lesson I will explain a Python Set which is an unordered collection of unique elements.

Let's learn List Comprehension a quick way to create new lists using a readable, one-line expression.

Let’s build a mini project using lists and dictionaries — a Contact Book.

Welcome to Section 6!
Until now, we’ve been writing all our code inside a single block.
But as programs grow, this becomes messy and hard to maintain.

This is where functions come in.

In this lesson you will learn how to define and call functions.

Let's see how to make functions more useful by accepting input (parameters) and returning output (return values).

In this lesson I will explain small, single-line functions called lambda functions or anonymous functions.

In this lesson we will take up three powerful functions used in Python for processing data: map, filter and reduce. These functions help process lists efficiently.

In this lesson we will take up the concept of modules and packages in Python.

Let’s build a small but useful project — a Unit Converter.

Welcome to Section 6!

In this section, we’re going to learn how Python works with files — something every real-world program needs to do.

In this lesson we will understand the process of reading from and writing to files.

In this lesson I will explain how to use the built-in csv module for handling csv files in Python.

In this lesson you will learn to use the built-in json module for handling json files.

Let’s build a practical mini project — a Student Records Manager using CSV files.

Welcome to Section 7!
In this section, we’re going to learn something that every programmer faces in his coding journey — errors.

In this lesson you will learn the most basic form of exception handling uses try and except.

Sometimes you want to raise your own errors when something is wrong. Let's see how that can be done.

In this lesson you will learn how to create your own exceptions using classes.

Let’s build a small project that uses error handling — a Login System.

Welcome to Section 8!

In this section, we’re moving into one of the most important concepts in modern programming — Object-Oriented Programming, or OOP.

A class is a blueprint or template.

An object is an actual thing created from that blueprint.

In this lesson we will learn about the concept of Inheritance which allows one class to take features from another class.

In this lesson we will learn about the concept of Polymorphism which allows a child class to redefine a method that already exists in the parent class.

In this lesson we will learn about the concept of Encapsulation which refers to restricting access to variables and methods.

In this lesson let's take a look at magic methods, also called dunder or double underscore methods which help give more functionality to the classes and allow objects to behave like built-in types.

Let’s build a practical OOP project — a Library Management System.

Welcome to Section 9!

In this section, we're moving beyond core Python and into libraries, which expand what Python can do.

In this lesson let’s begin with the library NumPy (Numerical Python) which is the foundational library for scientific computing in Python.

In this lesson let’s learn Pandas, the most important library for data analysis.

In this lesson let’s visualize data using Matplotlib which is a plotting library for the Python programming language and its numerical mathematics extension NumPy.

Let’s build a practical project — a Sales Data Visualizer.
