This error tells you that the module "automata.py" does not have a 
global-level object called "find_all_matches".

If you look at the module, you will see it does not have a global-level 
object called "find_all_matches", exactly as Python tells you. To fix 
this, you need to either:

(1) Give the automata module a function "find_all_matches" that does 
what you expect it to do; or

(2) Change automata_test2 to create a DFA instance, then call the 
find_all_matches method in that instance. Something like:

instance = automata.DFA(start_state)
instance.find_all_matches("word", k, lookup_func)
