choices = ["da","ja"]
truth = random.choice(choices)
false =[c for c in choices if c != truth]
false = false[0]
gods = [lambda: truth, lambda: false, lambda: random.choice(choices)]
a = random.choice(gods)
b = a
while b == a:
  b = random.choice(gods)
c = a
while c == a or c == b:
  c = random.choice(gods)
# at this point, a, b, and c are randomly selected gods. Each returns "ja", or "da", to mean true or false, but that's also random
