Duplicate Zeros

"Sometimes, zeros resemble very tasty donut. And every time we finish a donut, we want another, and then another, and then another..."
You are given list of integers (int). Your task in this mission is to duplicate (..., 🍩, ... --> ..., 🍩, 🍩, ...) all zeros (think about donuts ;-P) and return the result as any Iterable. Let's look on the example:
Input: List of integers (int).
Output: A list on another Iterable (tuple, generator, iterator) of integers (int).
Examples:
assert list(duplicate_zeros([1, 0, 2, 3, 0, 4, 5, 0])) == [ 1, 0, 0, 2, 3, 0, 0, 4, 5, 0, 0, ] assert list(duplicate_zeros([0, 0, 0, 0])) == [0, 0, 0, 0, 0, 0, 0, 0] assert list(duplicate_zeros([100, 10, 0, 101, 1000])) == [100, 10, 0, 0, 101, 1000]
If you have solved this mission, you can enjoy a 🍩 with peace of mind!=)
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
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.
