21. What is multiple inheritance in Perl?When more than two different inheritance takes place in a single program. When a class inherits more than two classes When two classes inherit properties from a single class None of theseAnswer: B) When a class inherits more than two classesExplanation...
Inheritance is a fundamental concept in object-oriented programming (OOP) that allows a class (called a subclass or derived class) to inherit properties and behaviors from another class (called a superclass or base class). In Python, a subclass can inherit attributes and methods from its superc...
Python is a high-level, general-purpose programming language known for its readability and simplicity. Learn the features, applications, and advantages of Python.
Tensor t is taken as an argument in flatten function and since reshape has to be done as the next part, -1 is passed as the second argument. The value should be based on the number of elements inside the tensor, and it equals the product of elements in the tensor. For example, if ...
Python supports multiple programming paradigms including imperative, procedural, object-oriented, and functional programming styles. Python is an extensible language. Additional functionality (other than what is provided in the core language) can be made available through modules and packages written in oth...
MRO is a mechanism to resolve the method to be executed when super notation is used. A common confusion occurs in case of multiple inheritance. What if a common method is implemented in multiple parents and it is called using super(), from which class should the method be called? This is...
What is a real-world example of encapsulation in popular programming languages other than Java? In Python, encapsulation can be implemented using naming conventions and property decorators. By convention, attributes or methods prefixed with an underscore (_) indicate that they are intended to be pri...
In languages like Java or Python, entities are represented through classes. A class acts as a blueprint for creating objects of that type. Each instance of a class becomes an entity with its own set of attributes and behaviors. What is the relationship between entities in object-oriented progr...
Reusability: The statement is parsed once, and can be efficiently executed multiple times with different parameter values. Improved security: The database can perform more optimizations since it knows more about the query in advance. You prepare a statement with PDO::prepare(), bind parameters usin...
polymorphism works by creating a relationship between classes using inheritance. when a superclass defines a method, its subclasses can override that method to provide their own implementation. at runtime, the appropriate method is called based on the actual type of the object. this dynamic binding...
