# --description--

Given a string of numbers separated by commas, return an array of the numbers sorted from smallest to largest.

# --hints--

`sort_numbers("3,1,2")` should return `[1, 2, 3]`.

```js
({test: () => { runPython(`
from unittest import TestCase
TestCase().assertEqual(sort_numbers("3,1,2"), [1, 2, 3])`)
}})
```

`sort_numbers("5,3,8,1,9,2")` should return `[1, 2, 3, 5, 8, 9]`.

```js
({test: () => { runPython(`
from unittest import TestCase
TestCase().assertEqual(sort_numbers("5,3,8,1,9,2"), [1, 2, 3, 5, 8, 9])`)
}})
```

`sort_numbers("12,61,49,80,19,50,77,38")` should return `[12, 19, 38, 49, 50, 61, 77, 80]`.

```js
({test: () => { runPython(`
from unittest import TestCase
TestCase().assertEqual(sort_numbers("12,61,49,80,19,50,77,38"), [12, 19, 38, 49, 50, 61, 77, 80])`)
}})
```

`sort_numbers("0,6,-19,44,-2,7,0")` should return `[-19, -2, 0, 0, 6, 7, 44]`.

```js
({test: () => { runPython(`
from unittest import TestCase
TestCase().assertEqual(sort_numbers("0,6,-19,44,-2,7,0"), [-19, -2, 0, 0, 6, 7, 44])`)
}})
```
