Nicola likes to categorize all sorts of things. He categorized a series of numbers and as the result of his efforts, a simple sequence of numbers became a deeply-nested list. Sophia and Stephan don't really understand his organization and need to figure out what it all means. They need your help to understand Nikolas crazy list.
There is a list which contains integers or
other nested lists which may contain yet more lists and integers which then… you get the idea.
You should put all of the integer values into one flat list.
The order should be as it was in the original list with string representation from left to right.
In this mission you should use the 'yield' to make your function a generator.
We need to hide this program from Nikola by keeping it small and easy to hide. Because of this, your code should be shorter than 140 characters (with whitespaces) .
Input data: A nested list with integers.
Output data: The one-dimensional list with integers.
flat_list([1, 2, 3]) == [1, 2, 3] flat_list([1, [2, 2, 2], 4]) == [1, 2, 2, 2, 4] flat_list([[], [4, [5, 6, , 6, 6, 6], 7]]) == [2, 4, 5, 6, 6, 6, 6, 6, 7] flat_list([-1, [1, [-2], 1], -1]) == [-1, 1, -2, 1, -1]
How it is used: This concept is useful for parsing and analyzing files with complex structures and the task challenges your creativity in writing short code.
0 ≤ |array| ≤ 100
∀ x ∈ array : -2 32 < x < 2 32 or x is a list
depth < 10
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
Configure your tool
checkio --domain=py config --key=
Sync solutions into your local folder
(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 --ff
checkio install-plugin --chromium
