Regular expression problems

A regular expression is compiled into a recognizer by constructing a generalized transition diagram called a Finite Automaton (FA). Finite automata can be Non-deterministic Finite Automata (NFA) or Deterministic Finite Automata (DFA). It is given by M = (Q, Σ, qo, F, δ). Where Q - Set of states Σ - Set of input symbols qo - Start stateThe regular expression "regex" is compiled with re.compile(regex) and the compiled object is saved in the object compiled_re.
