# Python: Return the symmetric difference between two iterables, without filtering out duplicate values

## Python List: Exercise - 242 with Solution

Write a Python program to get the symmetric difference between two iterables, without filtering out duplicate values.

- Create a set from each list.
- Use a list comprehension on each of them to only keep values not contained in the previously created set of the other.

**Sample Solution:**

**Python Code:**

```
def symmetric_difference(x, y):
(_x, _y) = (set(x), set(y))
return [item for item in x if item not in _y] + [item for item in y
if item not in _x]
print(symmetric_difference([10, 20, 30], [10, 20, 40]))
```

Sample Output:

[30, 40]

**Floor Division:**

When we speak of division we normally mean (/) float division operator, this will give a precise result in float format with decimals.

For a rounded integer result there is (//) floor division operator in Python. Floor division will only give integer results that are round numbers.

print(1000 // 300) print(1000 / 300)

Output:

3 3.3333333333333335
