Python Set symmetric_difference() Method with Examples

Prerequisite:

Set symmetric_difference() Method in Python:

The symmetric_difference() method returns a set that includes all items from both sets but excludes items that are present in both sets.

That means the returned set contains a mix of items that aren’t in either set.

For Example:

If P and Q are two distinct sets. The Symmetric difference of given two sets is :

The set of elements that are in either P or Q but not in their intersection is the symmetric difference.

Let P={4, 5, 6, 7}

Q={5, 6, 8, 9}

Here {5, 6} are the common elements in both sets. so, we exclude them.

The symmetric difference of P and Q = {4, 7, 8, 9}

Syntax:

set.symmetric_difference(set)

Parameters

set: This is Required. The set to look for matches in.

Examples:

Example1:

Input:

Given first set = {10, 20, 50, 60, 30}
Given second set = {20, 60, 80}

Output:

The symmetric difference of first and secondset =  {10, 80, 50, 30}

Example2:

Input:

Given first set = {4, 5, 6, 7}
Given second set = {5, 6, 8, 9}

Output:

The symmetric difference of first and secondset =  {4, 7, 8, 9}

Set symmetric_difference() Method with Examples in Python

Using Built-in Functions (Static Input)
Using Built-in Functions (User Input)

Method #1: Using Built-in Functions (Static Input)

Approach:

Give the first set as static input and store it in a variable.
Give the second set as static input and store it in another variable.
Give the third set as static input and store it in another variable.
Get the symmetric difference of the first set and second set using the symmetric_difference() method and print it.
Get the symmetric difference of the second set and first set using the symmetric_difference() method and print it.
Get the symmetric difference of the first set and third set using the symmetric_difference() method and print it.
The Exit of the Program.

Below is the implementation:

# Give the first set as static input and store it in a variable.
fst_set = {10, 20, 50, 60, 30}
# Give the second set as static input and store it in another variable.
scnd_set = {20, 60, 80}
# Give the third set as static input and store it in another variable.
thrd_set = {}
# Get the symmetric difference of the first set and second set using
# the symmetric_difference() method and print it.
print("The symmetric difference of first and secondset = ",
      fst_set.symmetric_difference(scnd_set))
# Get the symmetric difference of the second set and first set using
# the symmetric_difference() method and print it.
print("The symmetric difference of second and firstset = ",
      scnd_set.symmetric_difference(fst_set))
# Get the symmetric difference of the first set and third set using
# the symmetric_difference() method and print it.
print("The symmetric difference of first and thirdset = ",
      fst_set.symmetric_difference(thrd_set))

Output:

The symmetric difference of first and secondset =  {10, 80, 50, 30}
The symmetric difference of second and firstset =  {80, 50, 10, 30}
The symmetric difference of first and thirdset =  {10, 50, 20, 60, 30}

Method #2: Using Built-in Functions (User Input)

Approach:

Give the first set as user input using set(),map(),input(),and split() functions.
Store it in a variable.
Give the second set as user input using set(),map(),input(),and split() functions.
Store it in another variable.
Give the third set as user input using set(),map(),input(),and split() functions.
Store it in another variable.
Get the symmetric difference of the first set and second set using the symmetric_difference() method and print it.
Get the symmetric difference of the second set and first set using the symmetric_difference() method and print it.
Get the symmetric difference of the first set and third set using the symmetric_difference() method and print it.
The Exit of the Program.

Below is the implementation:

# Give the first set as user input using set(),map(),input(),and split() functions.
# Store it in a variable.
fst_set = set(map(int, input(
   'Enter some random Set Elements separated by spaces = ').split()))
# Give the second set as user input using set(),map(),input(),and split() functions.
# Store it in another variable.
scnd_set = set(map(int, input(
   'Enter some random Set Elements separated by spaces = ').split()))
# Give the third set as user input using set(),map(),input(),and split() functions.
# Store it in another variable.
thrd_set = set(map(int, input(
   'Enter some random Set Elements separated by spaces = ').split()))
   
# Get the symmetric difference of the first set and second set using
# the symmetric_difference() method and print it.
print("The symmetric difference of first and secondset = ",
      fst_set.symmetric_difference(scnd_set))
# Get the symmetric difference of the second set and first set using
# the symmetric_difference() method and print it.
print("The symmetric difference of second and firstset = ",
      scnd_set.symmetric_difference(fst_set))
# Get the symmetric difference of the first set and third set using
# the symmetric_difference() method and print it.
print("The symmetric difference of first and thirdset = ",
      fst_set.symmetric_difference(thrd_set))

Output:

Enter some random Set Elements separated by spaces = 3 4 5 6
Enter some random Set Elements separated by spaces = 3 7 8 9
Enter some random Set Elements separated by spaces = 9 5 7 1
The symmetric difference of first and secondset = {4, 5, 6, 7, 8, 9}
The symmetric difference of second and firstset = {4, 5, 6, 7, 8, 9}
The symmetric difference of first and thirdset = {1, 3, 4, 6, 7, 9}
