python - Return a tuple of arguments to be fed to string.format()

Question

Currently, I'm trying to get a method in Python to return a list of zero, one, or two strings to plug into a string formatter, and then pass them to the string method. My code looks something like this:

class PairEvaluator(HandEvaluator):
  def returnArbitrary(self):
    return ('ace', 'king')

pe = PairEvaluator()
cards = pe.returnArbitrary()
print('Two pair, {0}s and {1}s'.format(cards))

When I try to run this code, the compiler gives an IndexError: tuple index out of range.
How should I structure my return value to pass it as an argument to .format()?

Answer 1

print('Two pair, {0}s and {1}s'.format(*cards))

You are missing only the star :D
