Oops concepts in Python include inheritance, encapsulation, polymorphism, and abstraction.
Inheritance allows a class to inherit attributes and methods from another class.
Encapsulation restricts access to certain components within a class.
Polymorphism allows objects to be treated as instances of their parent class.
Abstraction hides complex implementation details and only shows the necessary features.
SQL queries are commonly used in frameworks for data manipulation and retrieval.
SQL queries are used to interact with databases within a framework.
Frameworks like Hibernate, Entity Framework, and Django ORM use SQL queries to perform database operations.
SQL queries can be written directly in code or generated by the framework based on object-relational mapping.
Examples: SELECT * FROM table_name WHERE condition, INSERT ...
Design patterns in Python are reusable solutions to common problems in software design.
Design patterns help in creating maintainable and scalable code.
Some common design patterns in Python include Singleton, Factory, Observer, and Strategy.
Each design pattern has its own purpose and implementation.
Design patterns promote code reusability and flexibility.
A closure is a function that has access to its own scope, the scope in which it was defined, and the global scope.
A closure is created when a function is defined inside another function.
The inner function has access to the variables and parameters of the outer function, even after the outer function has finished executing.
Closures are useful for creating private variables and functions in JavaScript.
They can also be us...
Encapsulation is the process of hiding internal details and providing a public interface for accessing and manipulating data.
Encapsulation bundles data and methods together into a single unit.
It helps in achieving data abstraction and data hiding.
By encapsulating data, we can control access to it and prevent unauthorized modifications.
Encapsulation promotes code reusability and maintainability.
Example: A class in objec...
Inheritance is a concept in object-oriented programming where a class inherits properties and behaviors from another class.
Inheritance allows for code reuse and promotes the concept of hierarchy.
The class that is being inherited from is called the superclass or base class.
The class that inherits from the superclass is called the subclass or derived class.
The subclass can access the public and protected members of the s...
Abstraction is the process of simplifying complex systems by focusing on essential details.
Abstraction involves hiding unnecessary details and exposing only relevant information.
It allows developers to create models or representations that capture the essential aspects of a system.
Abstraction helps in managing complexity, improving code reusability, and enhancing maintainability.
For example, in object-oriented programm...
Polymorphism is the ability of an object to take on many forms. It allows objects of different classes to be treated as the same type.
Polymorphism is a fundamental concept in object-oriented programming.
It enables code reusability and flexibility.
Polymorphism can be achieved through method overriding and method overloading.
Example: A parent class Animal can have multiple child classes like Dog, Cat, and Bird. They can ...

Oops concept in Java refers to Object-Oriented Programming principles like Inheritance, Encapsulation, Polymorphism, and Abstraction.
Inheritance allows a class to inherit properties and behavior from another class.
Encapsulation involves bundling data and methods that operate on the data into a single unit.
Polymorphism allows objects to be treated as instances of their parent class.
Abstraction hides the implementation d...
