If a dictionary key has a Python list as its value, you can read the values
one by one in the list using a for-loop like in the following.
d = {k: [1,2,3]}
for v in d[k]:
print(v)
No tutorial describes this, why?
What is the Python explanation for this behaviour?
Sorry... why is this a surprise? If an object is iterable, you can
iterate over it.
>>> d = {'key': [1, 2, 3]}
>>> type(d['key'])
<class 'list'>
>>> val = d['key']
>>> type(val)
<class 'list'>
>>> for v in val:
... print(v)

1
2
3
