而且里面有些地方我不太清楚是什么意思，比如
float(fre_ + 1) / (index_word_pre + word_num_allClass)这里，难道这是计算tf-idf?但是tf-idf的公式好像不是这样的吧。- 这里最要是利用贝叶斯分类，但我看了2小时终于看到最后，发现在
getPofClass函数里面用了一个math.log(float(p), 2)计算p值，难道p值不是用P(B|A) = (P(A|B)P(B))/(P(A))这个公式吗？math.log是计算什么的呢？ - 我发现在
bayesclassifier.py的nativeTest里面似乎是有计算贝叶斯的，但被注释掉，而且在99行dir_path = os.path.join(os.path.dirname())似乎漏了一个参数
