# List Beautify

Let's assume, you are given a list of lists of positive/negative integer/float numbers, for example - [[1, 2, 10, 150], [10, 2, 1000, 2], [1, 120, 1, 1000]]. It's always correctly filled: has at least one non-empty inner list.

When you print it as a single object, you receive

 ```[[1, 2, 10, 150], [10, 2, 1000, 2], [1, 120, 1, 1000]] ```
or row by row:
 ```[1, 2, 10, 150] [10, 2, 1000, 2] [1, 120, 1, 1000] ```

Your function should return something from both views and improved: a single string (multiline if more than one inner list), where numbers in columns should be right-aligned. There must be exactly one whitespace between the longest number in a column incl. minus (if present) and the previous comma in a row. All rows of the same length, wrapped together in the list brackets.

 ```[[ 1, 2, 10, 150], [10, 2, 1000, 2], [ 1, 120, 1, 1000]] ```

Isn't it beautiful now 😍?

Input: List of lists of numbers.

Output: String.

Examples:

```assert (
list_beautify([[1, 2, 10, 150], [10, 2, 1000, 2], [1, 120, 1, 1000]])
== "[[ 1,   2,   10,  150],\n [10,   2, 1000,    2],\n [ 1, 120,    1, 1000]]"
)
assert list_beautify([[1, 10, 100, -1000]]) == "[[1, 10, 100, -1000]]"
assert (
list_beautify([[1, 1, 1, 1, 1], [1, 1, 1, 1, 1], [1, 1, 1, 1, 1]])
== "[[1, 1, 1, 1, 1],\n [1, 1, 1, 1, 1],\n [1, 1, 1, 1, 1]]"
)
assert (
list_beautify([[1, 1, -1, 1, 1], [1, 1, 1, 1, 1], [1, 1, 1, 1, 1]])
== "[[1, 1, -1, 1, 1],\n [1, 1,  1, 1, 1],\n [1, 1,  1, 1, 1]]"
)
```

CheckiO Extensions

CheckiO Extensions allow you to use local files to solve missions. More info in a blog post.

In order to install CheckiO client you'll need installed Python (version at least 3.8)

Install CheckiO Client first:

`pip3 install checkio_client`

`checkio --domain=py config --key=`

Sync solutions into your local folder

`checkio sync`

(in beta testing) Launch local server so your browser can use it and sync solution between local file end extension on the fly. (doesn't work for safari)

`checkio serv -d`

Alternatevly, you can install Chrome extension or FF addon

`checkio install-plugin`
`checkio install-plugin --ff`
`checkio install-plugin --chromium`

Read more here about other functionality that the checkio client provides. Feel free to submit an issue in case of any difficulties.
