# Python Tutorial: Understanding the Symmetric_difference_update() Method in Sets

Python is a high-level programming language which is widely used in development for both applications and web development. It is known for its flexibility and ease of use. One of the main features of Python is its collection of built-in functions and methods, which are used to perform various tasks. In this Python tutorial, we will be discussing the symmetric_difference_update() method in sets. This method is used to find the differences between two sets and update one set with the differences.

## What is Symmetric_difference_update()

The symmetric_difference_update() method is used to find the difference between two sets. It takes two sets as parameters and returns a new set which consists of the elements that are present in either of the two sets but not in both. This means that it will return the elements which are present in one set but not the other. The method also updates the set on which it is called by adding the elements which are present in the other set but not in the one on which the method is called. This means that it will add the elements to the original set which are present in the other set but not in the original set.

## Syntax

The syntax of the symmetric_difference_update() method is as follows:`set1.symmetric_difference_update(set2)`Here, set1 and set2 are two sets that are to be compared and updated with the difference.

## Example

Let us consider an example to understand the symmetric_difference_update() method better. Consider two sets:`set1 = {1, 2, 3, 4, 5}set2 = {4, 5, 6, 7, 8}`Now, let us apply the symmetric_difference_update() method on these two sets:`set1.symmetric_difference_update(set2)`The result of this operation will be a new set which consists of the elements that are present in either of the two sets but not in both, i.e. the elements which are unique to each set. In this case, the result will be {1, 2, 3, 6, 7, 8}. The set1 will also be updated with the elements present in set2 but not in set1, i.e. {6, 7, 8}.Therefore, the set1 after the operation will be {1, 2, 3, 4, 5, 6, 7, 8}.

## Return Value

The symmetric_difference_update() method does not return any value. It only updates the set on which it is called.

The symmetric_difference_update() method is very useful when it comes to finding the difference between two sets. It is also a very efficient way of updating one set with the elements which are present in another set. This saves time and effort as it eliminates the need to manually update the set.

The symmetric_difference_update() method is not suitable for large sets as it requires a lot of time and memory to update the set. Also, the method does not work if the sets have duplicate elements.

## Suggestions to Improve Python Coding

The following are some suggestions to improve your python coding skills related to the symmetric_difference_update() method:

• Understand the basic concepts of sets and how they work.
• Familiarize yourself with the different methods of sets.
• Practice coding different examples to understand the symmetric_difference_update() method better.
• Make sure you understand the parameters and their syntax before using the method.
• Learn about other methods which can be used to find the difference between two sets.

The symmetric_difference_update() method is a useful and efficient way of finding the difference between two sets and updating one set with the difference. It is important to understand the syntax and parameters of the method before using it. It is also important to understand the advantages and disadvantages of the method. With practice and familiarity, you can easily use the symmetric_difference_update() method in your python programs.
