Re: If a dictionary key has a Python list as its value!

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)
