[Tutor] appending/updating values dict key value pairs

[Sivaram Neelakantan]

What's the best way to append to the list which is the value to a dict
key?

I did the following based on the docs and I'm not sure why it works

>>> b = { 'a': [4, 5]} 
>>> list.append(b.get('a'),'c')
>>> b
{'a': [4, 5, 'c']}
>>> 


as in, shouldn't it be

b['a'] = list.append(b.get('a'),'c')

which doesn't seem to work.
