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

  Variable Declaration and Definition in Python Unlike C/C++ and Java, Python uses dynamic typed variables. What does it mean? To know answer of the question see the variable declaration in C. int x; It means you declare a variable x then compiler allocates memory and assigns a garbage value to x. You can initialize

List in Python List in Python is a very powerful data structure which can store any type of data which is supported by Python. It is created using square bracket for example l=[2,4,5.2,’post’,’network’,10] this statement creates a list object of class list, and indexes objects as l[0], l[1], l[2], l[3], l[4] and l[5]. If you

Sets Set is a collection of well-defined objects. Set’s Representation Basically, there are two ways of a set representation. Types of Set 1-Null Set A set is called null set if it is empty or it does not have any elements and it is denoted by fi. 2-Singelton Set A set is called singleton if
