In Python, the raise keyword is primarily used for exception handling. Exception handling is responsible for handling exceptions or errors so that the system does not fail due to incorrect code. The raise keyword generates an error and halts the program’s control flow. It is used to invoke the current exception handler so that it […]

Types of Inheritance depend upon the number of child and parent classes involved. There are four types of inheritance in Python: Single Inheritance Multiple Inheritance Multilevel Inheritance Hierarchical Inheritance Single Inheritance: Single inheritance allows for the inheritance of properties from a single parent class by a derived class, allowing for the reuse of existing code […]

Inheritance is a fundamental idea in object-oriented programming (OOP) languages. By deriving a class from another class, you can use this mechanism to build a hierarchy of classes that share a set of properties and methods. Benefits of inheritance include: It accurately depicts real-world relationships. It offers a code’s reusability. We don’t need to keep […]

A function is a collection of statements that accept input, perform some specific computation, and return output. The idea is to combine some frequently or repeatedly performed tasks into a function so that instead of writing the same code for different inputs, we can call the function. All functions written by the user fall into […]

There may be times when you need to execute a block of code several times. A loop statement allows us to repeat a statement or group of statements. To handle looping requirements, the Python programming language provides the following types of loops. for loop: Sequential traversal is accomplished with for loops. This loop repeats a […]
