#Half In

<!-- language-all: lang-py -->

This bot always bids half of what it has left.

    class half_in:
      def __init__(self):
        self.money = 0
      def play_round(self, winner, win_amount):
        # Default actions:
        #  Collect 500 dollars
        self.money += 500
        #  If it was the winner: subtract the win_amount from his money
        if winner == 0:
          self.money -= win_amount

        # Bid half what it has left:
        return self.money / 2

I never program in Python, so if you see any mistakes let me know..
