Sets in Python

Introduction

Sets in python are a collection of data structure which is comprised of unordered elements, unique elements, and indexed elements. All these elements are unique in their own way that means they are present one at a time only. Values belong to any type of data except index that unable the users from performing any kind of indexing operation like slicing on the index. The use of sets in python is made irrespective of the data order but what matters is that the element of data must be unique.

 Operations of Python Sets

Operation of Python sets!

• Finding the length & accessing the elements
•  Adding or updating the element sets
• Removing or deleting the element sets
• Union of sets
• Intersection of sets
• Difference of sets

FINDING THE LENGTH OF A SET

Length of the set refers to the number of elements presented in the set and in order to achieve this you can make use of len(). 

ACCESSING ELEMENTS OF A SET

The elements of the set are not accessed with the help of index numbers rather they are accessed by looping through it.

ADDING ELEMENTS TO A SET

The elements are added to a set with the help of following functions;

·    The first function is added () that allow the users to add a single element to the set.

·    Second function is update() and this function is used when there is a need to add more than on element.

REMOVING ELEMENTS FROM A SET

The elements from the set are removed through following functions;

·        Remove () - This is the first function that removes the set from a specified parameter.

·       Discard() - This is used when the user is not sure whether the element is actually present in the set or not then discard() function is used.

·      Pop() – This function is particularly used when a user wants to remove the random element from the set.

UNION SETS

·        Union sets are referred to as ‘Concatenation()’ of two or more sets into a single set and this operation are practiced using two ways that are; pipeline symbol and the union method.

INTERSECTION OF SETS

·      The intersection of two or more sets forms a complete new set which is comprised of only common elements in those particular sets.

·        his is done through two ways; using ‘&’ symbol and using the ‘intersection()’.

DIFFERENCE OF SETS

·       The difference between sets produces a whole new set consisting of those elements that are present in one of those sets only.

·       This is done with the help of using ‘-‘ & using difference().
