Study Notes

Python

Python is a high-level, general-purpose programming language.
Interpreted language: code is executed line by line.
Dynamically typed: data types are checked at runtime, not compile time.
Readable syntax: emphasizes code clarity.
Extensive libraries and frameworks for various applications.
Widely used in web development, data science, machine learning, automation, and more.
Excellent for beginners due to its ease of use and readability.

Data Structures

Data structures organize and store data efficiently.
Common data structures in Python: lists, tuples, dictionaries, sets.
Lists: ordered, mutable sequences of items.
- Can contain elements of different types.
- Accessed by index (starting at 0).
- Methods for adding, removing, and modifying elements.
Tuples: ordered, immutable sequences of items.
- Similar to lists but cannot be changed after creation.
- Useful for representing fixed collections of data.
Dictionaries: key-value pairs, unordered collection of items.
- Keys must be immutable (e.g., strings, numbers).
- Values can be any data type.
- Accessed by keys.
Sets: unordered collections of unique items.
- Useful for membership testing and eliminating duplicates.
- Support mathematical operations like union, intersection, etc.

Object-Oriented Programming (OOP) in Python

OOP is a programming paradigm that organizes software design around 'objects'.
Objects encapsulate data (attributes) and methods (functions) that operate on that data.
Key OOP concepts in Python:
- Classes: blueprints for creating objects.
- Objects (instances): specific occurrences of a class.
- Attributes: data associated with an object.
- Methods: functions that operate on an object's attributes.
- Encapsulation: bundling data and methods that operate on the data within a class.
  - Helps in controlling access to data.
- Inheritance: creating new classes (child classes) from existing ones (parent classes).
  - Child classes inherit attributes and methods from the parent.
  - Extends and builds upon existing functionalities.
- Polymorphism: the ability of objects of different classes to respond to the same method call in their own way.
Example demonstrating a simple class definition

class Dog:
    def __init__(self, name, breed):
        self.name = name
        self.breed = breed

    def bark(self):
        print("Woof!")

my_dog = Dog("Buddy", "Golden Retriever")
print(my_dog.name) 
my_dog.bark()

Python supports multiple inheritance, where a class can inherit from multiple parent classes.
Python uses special methods (e.g., __init__, __str__) to customize object behavior.
Abstraction: creating simplified representations of complex objects, simplifying code and enhancing maintainability.
