# Python Exercise: Create a symmetric difference

## Python sets: Exercise-9 with Solution

Write a Python program to create a symmetric difference.

From Wikipedia, in mathematics, the symmetric difference, also known as the disjunctive union, of two sets is the set of elements which are in either of the sets and not in their intersection. The symmetric difference of the sets A and B is commonly denoted by

For example, the symmetric difference of the sets **{1,2,3} and {3,4} is {1,2,4}**.

**Sample Solution**:-

**Python Code:**

```
setx = set(["apple", "mango"])
sety = set(["mango", "orange"])
#Symmetric difference
setc = setx ^ sety
print(setc)
```

Sample Output:

{'apple', 'orange'}
