Basic While Loop SyntaxThe while loop in Python repeatedly executes a block of code as long as a specified condition evaluates to true. This construct is ideal for scenarios where the number of iterations is not predetermined.counter = 0 while counter < 5: print(f"Current iteration: {counter}") counter += 1 print("Loop completed!")The ...

Annotations provide a mechanism for attaching metadata to code. To declare an annotation, use the annotation modifier before a class. annotation class CustomAnnotation Additional characteristics of an annotation can be specified by annotating the annotation class itself with meta-annotations. @Target defines the types of elements the annotati ...

A list is an ordered, mutable collection that can hold elements of any type, including other lists. Creating Lists Lists can be created through direct definition, for loops, and list comprehensions. Direct Definition Use square brackets []. sample_list = [1, 2, 'hello', [3, 4], (5,), {'data': 100}] Using a For Loop num_list = [] for j in range ...

Object-Oriented Programming Overview In the Java programming language, Object-Oriented Programming (OOP) serves as the foundational paradigm. A class acts as a blueprint or template, while an object is a concrete instance of a class. The core characteristics that define OOP are encapsulation, inheritance, and polymorphism. Class Structure Clas ...

Conditional execution in Python directs program flow by evaluating Boolean expressions. Code blocks execute only when their associated condition resolves to True. In Python, any non-zero numerical value or non-empty sequence is considered True; zero, None, and empty sequences evaluate to False. The foundational if-else construct has this syntax ...

Basic Types Primitive types in TypeScript include number, string, boolean, null, undefined, and symbol. Object types encompass arrays, objects, functions, and more. You can define custom complex object types using type aliases. // Primitive types: number/string/boolean/null/undefined/symbol // Object types: arrays, objects, functions, etc. ty ...
