All the print statements in the quiz examples put out literal strings (like this one: print("A")Β ), so no variables or functions or needed.

You task is to anticipate how the program flow will be redirected by the "try" and "except" statements, and determine which of the print statements will run. From there, you can determine what the output will be since each statement that runs will output a single letter.

You'll want to walk through the code step by step for each question. Try going one line at a time and thinking about what would happen when it runs. This method should work for both questions, but here is an example below.

print("A") # does this print?
try:
    result = 5 + 5 # does this raise a ValueError or TypeError?
    print("B") # depending on whether an error is raised, does this run?
except ValueError:
    print("C") # did you trigger a ValueError?
except TypeError:
    print("D") # did you trigger a TypeError?
else:
    print("E") # if no errors were triggered, does this run?
print("F") # does this print?

Hopefully that gives you a place to start, but please let me know if you still have questions and we can walk through a solution. Happy coding!
