Given an iterable of ints , create and return a new iterable whose first two elements are the same as in items, after which each element equals the median of the three elements in the original list ending in that position.
Wait...You don't know what the "median" is? Go check out the separate "Median" mission on CheckiO.
Input: Iterable of ints.
Output: Iterable of ints.
list(median_three([1, 2, 3, 4, 5, 6, 7])) == [1, 2, 2, 3, 4, 5, 6] list(median_three()) ==  list(median_three([-1, 0, 1])) == [-1, 0, 0]
The mission was taken from Python CCPS 109 Fall 2018. It’s being taught for Ryerson Chang School of Continuing Education by Ilkka Kokkarinen
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
