 It looks like you have not got a Python Dot yet. Perhaps you mean:  
  mydict = {} mydict ['A'] = {'count': 3, 'letters': ['x', 'y', 'z']} Mydict ['B'] = {'Count': 2, 'Letters': ['m', 'n']}   
  mydict  is a dictionary               Counting is a bit of a thing in storage, because you can only use  len ()  if you need it, you can do it like this: <"" "" "" "" '' '' '' '' '' '']} Print minded ['a']
