Your function should create a list of lists, that represents a two-dimensional grid with the given number of rows and cols.
This grid should contain integers (int) from start to start + rows * cols - 1 in ascending order, but the elements of every odd-index row have to be listed in descending order, so that when read in ascending order, the numbers zigzag through the two-dimensional grid.
Input: Two integers (int) - rows and columns. One optional integer (int) - start.
Output: List of lists.
assert create_zigzag(3, 5) == [[1, 2, 3, 4, 5], [10, 9, 8, 7, 6], [11, 12, 13, 14, 15]] assert create_zigzag(5, 1) == [, , , , ] assert create_zigzag(3, 3, 5) == [[5, 6, 7], [10, 9, 8], [11, 12, 13]]
The mission was taken from Python CCPS 109 Fall 2018. It is 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
