I'm using a config.yaml and want to read a list of integers in "week":

{'worksheet_name': 'March 2024',
 'week': [12, 13],
 'name': 'John Doe',
 'username': 'jd9003'}

Reading this yaml with

with open("config.yaml", encoding='utf8') as f:
    cfg = yaml.load(f, Loader=yaml.FullLoader)

strangely leads to this value

week: [[12, 13]]

and not to

week: [12, 13]

Which format should be used for a list of int in yaml?

If i run your code i don't get week: [[12, 13]].

import yaml

with open("config.yaml", encoding='utf8') as f:
    cfg = yaml.load(f, Loader=yaml.FullLoader)

Test.

>>> cfg
{'name': 'John Doe',
 'username': 'jd9003',
 'week': [12, 13],
 'worksheet_name': 'March 2024'}

>>> cfg['week']
[12, 13]
>>> cfg['week'][1]
13
>>> type(cfg['week'][1])
<class 'int'>

So get back Python data structure a dictionary contains a working list of integers.

file used: cofig.yaml

Output:
{'worksheet_name': 'March 2024',
 'week': [12, 13],
 'name': 'John Doe',
 'username': 'jd9003'}

Error found and request for forgiveness attached - for some reason, the assignment looked like this (and is strangely executable without errors):

week = [cfg['week']]
