Sets are known as python data types which are used to store values in a sequenceꓸ lists, tuples and dictionary also stores values like inset but the only main difference in all of this is set store unordered values and cannot have multiple occurrences or duplicate value in itꓸ
Benefits of python sets:
-
Sets cannot have duplicate value in a listꓸ therefore they had to be removed or tuple for processing the theory operations like intersection such as in mathꓸ
Here you will find some of the topics regarding python sets and its set theoryꓸ
-
Processing a set: sets are of variable sequence which is of unordered valueꓸ
First, you need to process by using set () in an empty setꓸ
Then process the set by passing it through a list to set ()
Hence, you will be able to see the set in an unordered wayꓸ mostly sets are used by a curly bracket which can be used only in the time of processing a set containing valueꓸ
The curly bracket when used without values only define to process a dictionary and not a setꓸ
-
Adding or removing values from a set: first, you would need to process or initialize a setꓸ
For adding values you would need to add to add the values to a setꓸ
You had to keep in mind that you can only add a value that is like a tuple to a set otherwise you are going to get an errorꓸ
And for removing the values various ways are given below:
1. You can use the discard method for removing a value from a setꓸ the main advantages for using this method is that you won’t get any key error even if you remove a value that is not from the setꓸ
2. You can use the remove method for removing a value from a setꓸ the disadvantages for using this method is you can get a key error if you try to remove a value that is not from the setꓸ
3. Using a pop method for removing and again returning in an arbitrary value from a setꓸ but using it in an empty set can cause a key errorꓸ
- Iterating through a set: it is possible to iterate or add value through a set as sets are in unordered wayꓸ
- Methods of removing all the values from a set: By using the clear method you can easily remove all the values from a setꓸ
- Removing duplicates from a list: two types of methods are used for removing duplicates from a list:
4. using a set for removing duplicates from the listꓸ
5. Removing duplicates in a sequence wise from the listꓸ
-
Transforming set into ordered values: by using the sorted function method you can get the value in an order form as set are in unordered formꓸ
Setting up various operation methods:
The main function of sets in python is computing math operations such as difference, union, intersection, and symmetric differenceꓸ various methods are used for performing this mathematical operationsꓸ mainly they are used by the data scientist and data engineerꓸ
- Difference: The difference in the sets of data scientist and data engineer is that the set of all values of a data scientist are not theirs in data engineerꓸ
- Union: they are known as the set of all the values of a data scientist or data engineerꓸ this union method can be used for finding all the unique values in data scientist and data engineerꓸ
- Intersection: they are known as the intersection of two sets in data engineer and data scientistꓸ they are the set of all values that are values of both data scientist and data engineerꓸ whereas if you want two sets that had an intersection and is empty then these two sets are known as disjoint setsꓸ
- Symmetric difference: they are known as set of all the values that are exact values of one set and not of bothꓸ
