Iteration in Python PYTHON by Ravinder Nath Rajotiya - April 19, 2022April 22, 20220 Iteration- for and while loop: Iterations are used for repetitive execution of the same block of code over and over. Loop or iteration are popular block of code in all the programming language like basic, PASCAL, C, JAVA, PHP and all others. They can be numeric or collection based. Type of Iteration There are two types of iteration: a) Definite iteration, in which the number of repetitions is specified explicitly in advance. This is implemented using the for loop. b) Indefinite iteration, in which the code block executes until some condition is met. This type of iteration is implemented using the while loop How to check if an object is iterable? we can check whether an object is itrable r not by passing it to the
Set in Python PYTHON by Ravinder Nath Rajotiya - April 10, 2022April 11, 20220 SETS in PYTHON A set is an unordered collection of items. Every element of a set is unique, i.e. there are no duplicate. A set itself is a mutable i.e. we can add or remove items in a set. Items of a set are immutable i.e. we cannot modify items of a set using its index. A set is declared using {} or in-built set() function How many items in a set: A set can have any number of integer, float, tuple, string types etc s={3,5,”Hello”, 3.14} What cannot be in a set: A set cannot have mutable elements like lists, sets or dictionaries as its elements. So it will be wrong to create a set: >>>s={3,5, [6,7], 3.14} error – set cannot have list as the set
