The sinking of the RMS Titanic is one of the most infamous shipwrecks in history. On April 15, 1912, during her maiden voyage, the Titanic sank after colliding with an iceberg, killing 1502 out of 2224 passengers and crew. This sensational tragedy shocked the international community and led to better safety regulations for ships.

内含三个必要文件，该脚本可完美识别深圳信用网的验证码。同时Img.py还能用于其他验证码的图像处理操作。

资源中包含完整的C4.5决策树算法Python代码和测试数据，其中有4个文件：C45.py是算法的实现代码，treePlotter.py是绘制决策树代码，PlayData.txt是样本数据，C45test.py用来构建、绘制并测试决策树，您可以运行该文件来依次进行决策树的构建、剪枝、绘制树型图，并对测试样本进行分类。

treePlotter 绘制树 机器学习matplotlib可能的绘制需要。哈哈哈哈 .... 积分太高啦
