Introduction to Python Programming

Study Notes

Introduction to Python

Python is a high-level, general-purpose programming language.
It's known for its clear syntax, readability, and large standard library.
Python is widely used in various domains, including web development, data science, machine learning, scripting, and automation.
Python's popularity stems from its versatility and ease of use, making it suitable for beginners and experienced programmers alike.

Key Features of Python

Interpreted Language: Python code is executed line by line by an interpreter, avoiding the need for compilation.
Dynamically Typed: Python variables do not need explicit type declarations.
Object-Oriented: Python supports object-oriented programming (OOP), allowing for modularity and reusability.
Extensive Libraries: Python boasts a vast collection of libraries for diverse tasks, such as numerical computation (NumPy), data analysis (Pandas), machine learning (Scikit-learn), and web development (Django, Flask).
Large and Active Community: Python has a large and active community supporting the language with ample resources, tutorials, and community forums for assistance.

Basic Data Types

Numbers: Integers (e.g., 10), floating-point numbers (e.g., 3.14), complex numbers (e.g., 2+3j).
Strings: Ordered sequences of characters enclosed in quotes (e.g., "Hello").
Lists: Ordered collections of items, mutable (e.g., [1, 2, "hello"]).
Tuples: Ordered collections of items, immutable (e.g., (1, 2, "hello")).
Dictionaries: Unordered collections of key-value pairs (e.g., {"name": "Alice", "age": 30}).
Booleans: Representing truth values (True or False).

Control Flow Statements

Conditional Statements (if-elif-else): Allow for conditional execution of code based on conditions.
Loops (for and while): Enable repetitive execution of code blocks.
Break and continue: Control the flow of loops.

Functions

Defining Functions: Creating reusable blocks of code.
Parameters and Arguments: Passing data into functions.
Return Values: Returning data from functions.

Modules and Packages

Modules: Bundled collections of functions.
Packages: Groups of related modules.
Importing Modules: Using functionality from external modules.

Object-Oriented Programming (OOP)

Classes: Blueprints for creating objects.
Objects: Instances of classes.
Methods: Functions defined within a class.
Encapsulation: Bundling data and methods within a class.
Inheritance: Creating new classes based on existing ones.
Polymorphism: Different objects responding in different ways to the same method call.

File Handling

Reading and Writing Files: Interacting with external files.
File Modes: Different ways to open files (read, write, append).

Exception Handling

Try-Except Blocks: Handling potential errors during program execution.
Raising Exceptions: Deliberately creating errors.

Data Structures

Lists: Ordered, mutable sequences of items.
Tuples: Ordered, immutable sequences of items.
Dictionaries: Unordered collections of key-value pairs.
Sets: Unordered collections of unique items.

Working with Libraries

NumPy: For numerical computations and array manipulation.
Pandas: For data analysis and manipulation.
Matplotlib: For creating static, interactive, and animated visualizations.
Scikit-learn: For machine learning tasks.
