YAML. Complex Structure
The 4th task in the series of missions about the YAML format will be devoted to a complex structure.
| YAML | Python/TypeScript |
|---|---|
|
A list element can be another list. |
|
- Alex
-
- odessa
- dnipro
- Li
|
[
"Alex",
[
"odessa",
"dnipro"
],
"Li"
]
|
|
A dictionary can also be an element of an list. |
|
- 67
-
name: Irv
game: Mario
-
- 56
|
[
67,
{
"game": "Mario",
"name": "Irv"
},
None/null,
56
]
|
|
A dictionary element can be another dictionary. |
|
name: Alex
study:
type: school
number: 78
age: 14
|
{
"age": 14,
"study": {
"type": "school",
"number": 78
},
"name": "Alex"
}
|
|
A list can also be an element of dictionary. |
|
name: Alex
study:
- 89
- 89
- "Hell"
age: 14
|
{
"age": 14,
"study": [
89,
89,
"Hell"
],
"name": "Alex"
}
|
|
And, of course, data can have more than one nesting level. |
|
name: Alex
study:
-
type: school
num: 89
-
type: school
num: 12
age: 14
|
{
"age": 14,
"study": [
{
"num": 89,
"type": "school"
},
{
"num": 12,
"type": "school"
}
],
"name": "Alex"
}
|
Input: Format string.
Output: An object (list/dictionary).
Examples:
assert yaml("- Alex\n-\n - odessa\n - dnipro\n- Li") == [
"Alex",
["odessa", "dnipro"],
"Li",
]
assert yaml("- 67\n-\n name: Irv\n game: Mario\n-\n- 56") == [
67,
{"game": "Mario", "name": "Irv"},
None,
56,
]
assert yaml("name: Alex\nstudy:\n type: school\n number: 78\nage: 14") == {
"age": 14,
"study": {"type": "school", "number": 78},
"name": "Alex",
}
assert yaml('name: Alex\nstudy:\n - 89\n - 89\n - "Hell"\nage: 14') == {
"age": 14,
"study": [89, 89, "Hell"],
"name": "Alex",
}
Precondition: The YAML 1.2 standard is being used.
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.
