Answer 1

If you always want your hint to contain 3 letters and the letters should be random, you could do:

hint = ["-"]*word_length

# Gets 3 random positions to have for the letters
positions = random.sample(range(0,word_length), 3)

# At those positions, change the "-" in hint to a letter.
for i in positions:
  hint[i] = chosen_word[i]

hint = "".join(hint)
print(hint)
