Binary Search Basic idea behind binary search is to divide sorted array in two parts, and check whether the element which divides the array is desired element . And if the desired element is found then stop the search, otherwise further divide the array until the desired element is not found. Step-Wise Pictorial Demonstration of […]

Classes and Objects in Python Class In object oriented programming, a class contains procedures and data members. And treated as an abstract data type. Object An object is an instance of a class.   In this post, I will discuss about classes and objects in Python programming. Let us start with creating a simple Python’s

Function- A function is a self-contained block of statement to perform a specific task. Basically, there are two types of function Library Functions These functions are are provided by a Python’s package and a user only need to call it in your program. User Defined Functions in Python As name indicates that a user will

Expectation  in statistics Expectation  in statistics is the weighted average of a random variable with its probability. Suppose you toss three coins, then think of event to turn heads up. Random variable associates number of occurrence of event to its probability. i.e. Expectation of random variable X is denoted by E(X). 1- Expectation of a

Array in Python Python does not have in-built array. However, in C/C++ and Java you have learnt array and have expectation that it would be in Python. Further, array also a very important data structure and needs in several applications and algorithm implementations. In Python, there are two ways to create an array. In this

Tuples in Python Tuples in Python are ordered collection of items(integer, float, string) which are immutable. The only difference from list you can notice that a tuple in Python is immutable. Further, it uses parenthesis to create a tuple. However, tuples can also be created without parenthesis separated by comma. Now open terminal or jupyter

  Decision making is fundamental in making a program. All programming languages provide in-built structure for it and Python is not exception. In this post, I will explain decision making using if else statements. Syntax if expression: Example of expressions x > 4 x < 4 x == 4 In Python you will write if
