This isn't a special case.
arr[2] to get the dictionary
arr[2]['a'] to get the value in the dictionary
'a' in arr[2] to find if there is such a key
arr[2].get('a') to get the value or None if the key isn't there
arr[2].get('a', 'd') to get a value even if the key isn't there
help(dict.get)
for key in arr[2]:
# to iterate over the keys
The exact same mechanisms are used no matter where you get the
dictionary from.
