pygameを使って画面に画像を描画しようとしていますが、画面に何も表示されませんか？

Question

私はまだPythonとプログラミング一般にかなり新しいです。私はシンプルなゲームを作るために私が使っている本と一緒にフォローしようとしています。私は私が言うことができる限り逐語的にプログラムをタイプしましたが、何らかの理由で私の船のイメージが表示されない限り、すべてがうまくいくように見えます。誰が問題が何であるかを見ていますか？私は対応するpygameバージョンでPython 3.4.3を使用しています。

while Trueループが多すぎます。 bg_draw()を実行して、最初にwhile Trueを実行し、決して離れることはありません。 ship()とShip()のほか
