Solution: Handling transactions gracefully

“

- [Instructor] Did you figure out the code? How was the experience? The challenge has a missing text in the Check class. Let's add the correct text, which is "Checking". We also need to add individual actions to our Transaction object. Let's add the identify action first. Type transaction.add (Identify()). Type transaction.add (Verify()). Type transaction.add (Check()). Let's also run the transaction and return the result as our last step. Transaction.run(). We are all set now. Let's test the code by clicking on Test my code. It produces the right string that says "Checking ...", well done.
