YAML. More Types
This is the second task on parsing YAML. It represents the next step where parsing gets more complicated. The data types, such as None and bool, are being added, and besides that, you’re getting the ability to use quotes in strings.
Here are some of the examples:
name: "Bob Dylan" children: 6 |
{ "name": "Bob Dylan", "children": 6 } |
name: "Alex \\"Fox\\"" children: 6 |
{ "name": "Alex \"Fox\"", "children": 6 } |
As you can see, the string can be put in quotes. It can be both double and single quotes.
name: "Bob Dylan" children: 6 alive: false |
{ "name": "Bob Dylan", "alive": False, "children": 6 } |
True and False are the keywords defining the bool type.
name: "Bob Dylan" children: 6 coding: |
{ "coding": None, "name": "Bob Dylan", "children": 6 } |
If no value is specified, it becomes undefined. There also is a keyword for this - None.
Input: A format string.
Output: An object (list/dictionary).
Examples:
assert yaml("name: Alex\nage: 12") == {"name": "Alex", "age": 12} assert yaml("name: Alex Fox\nage: 12\n\nclass: 12b") == { "name": "Alex Fox", "age": 12, "class": "12b", } assert yaml('name: "Alex Fox"\nage: 12\n\nclass: 12b') == { "name": "Alex Fox", "age": 12, "class": "12b", } assert yaml('name: "Alex \\"Fox\\""\nage: 12\n\nclass: 12b') == { "name": 'Alex "Fox"', "age": 12, "class": "12b", }
Precondition: YAML 1.2 is being used with JSON Schema.
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:

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.
