Sometimes, we want to compute list difference with Python.

In this article, we’ll look at how to compute list difference with Python.

### How to compute list difference with Python?

To compute list difference with Python, we can use the `-`

operator with sets.

For instance, we write:

```
A = [1, 2, 3, 4]
B = [2, 5]
x = list(set(A) - set(B))
print(x)
```

We create sets from `A`

and `B`

with the `set`

functions.

Then we get the difference between the 2 sets with the `-`

operator.

Finally, we convert the returned set difference back to a list with `list`

and assign that to `x`

.

Therefore, `x`

is `[1, 3, 4]`

.

### Conclusion

To compute list difference with Python, we can use the `-`

operator with sets.
