## 54. How to deduplicate str lists?

You can use KCL to deduplicate lists of strings as shown in the code snippet below:

```python
to_set = lambda items: [str] {
[item for item in {item = None for item in items}]
}

data = to_set(["aa", "bb", "bb", "cc"])
dataIsUnique = isunique(data)
```

After running above script, You'll get output like this:

```bash
data:
- aa
- bb
- cc
dataIsUnique: true
```
