A substring is a sequence of characters within a String. The following are the methods in Python to check if a string contains another string i.e. substring. By using find() method By using in operator By using count() method By using str.index() method By using operator.contains() method Method 1: By using find() method The method …

Python arrays can be sorted using different sorting algorithms, varying in their runtime and efficiency based on the algorithm chosen. We investigate some of these approaches towards sorting array elements. Using sorted() on Python iterable objects Python uses some extremely efficient algorithms for performing sorting. The sorted() method, for example, uses an algorithm called Timsort …
String in Python has built-in functions for almost every action to be performed on a string. Python String capitalize() function is used to convert only the first character to the uppercase letter, rest all characters are lowercase. Key Points : Return Type: String Parametric Values: No parameters can be parsed onto capitalize() function. Converts only …
Python has four built-in data types data, list, tuple, dictionary, and set. These data types can store multiple collections of data. A list is an ordered collection of data, it is a type of array that can store duplicate values, it is dynamic in size and mutable, and its elements can be accessed with their …
Polymorphism means having vivid or different forms. In the programming world, Polymorphism refers to the ability of the function with the same name to carry different functionality altogether. It creates a structure that can use many forms of objects. This permits functions/arguments to use entities of different types at different times. In object-oriented programming, Polymorphism …
Operator Overloading is the phenomenon of giving alternate/different meaning to an action performed by an operator beyond their predefined operational function. Operator overloading is also called Operator Ad-hoc Polymorphism. Python operators work for built-in classes. But the same operator expresses differently with different types. For example, The + operator will perform arithmetic addition on two numbers, …
Operators are used to performing operations on values and variables. These symbols carry out all kinds of computations. The value on which the operator operates on is known as Operand. In Python, bit-wise operators are used to performing calculations on integers according to the bits. The integers are converted into binary and then bit by bit …
Operators in Python are used to execute or manipulate certain tasks. Python comparison operators, also known by the name relational operators, are used in comparing two values and to apply conditions respectively. Here there can be two possible outputs, either True or False. Types of Comparison Operators in Python There are 6 types of comparison …
Python programming is a great tool to evaluate and make manipulations. In this article, We will be learning a simple command-line calculator program in Python 3. We’ll be using mathematical operators, Conditional statements, functions and handle user input to make our calculator. Prerequisites The system should have Python 3 installed on the local computer and have a …
Object-oriented programming (OOP) refers to the software design wherein programmers define the data type of a data structure, and the types of functions that can be applied to the data structure. This paradigm provides functionalities and behavior pattern to the structure of data. This paradigm maps and models real-world things together and describes a relationship …
