Python Turtleが正しく描画されない

Question

私はこのプログラムを作成してフラグを作成しましたが、最近実行しようとしましたが、もともとコード化していたにもかかわらず何らかの理由で動作しませんでした。縞模様は上手く描けるが、青い正方形と星になるとカメのポインタはどこにも動かない。私はPython 2.7.11を使用していますが、これは1年前に書かれたので、それがうまくいかない理由です。私は使用していたPythonのバージョンを覚えていません。

Answer 1

ここにあなたの問題です：

私はこのプログラムは、そのため除算演算子は、Python 2とPython 3の間に働く別の方法でのpython 2.7.11

をします使用していますPython3で動作する場合にのみ正しく動作します。証明：

Python2では、除算は切り捨て：

3/2 => 1.5ちょうどのpython3でコードを実行し、それが動作するはずです：のpython3で3/2 => 1
は、部門は常にfloatを生成します。
