输出所有可能的候选项集 Ck的算法有错误吧,例如输入{0,1,2}, {1,2,3}K=4,此时应该有输出{0,1,2,3},提供的算法只比较列表的前两项,L1==L2才会输出
Sorry, something went wrong.
生成候选集的 createC1(dataSet)函数返回值应改成return list(map(frozenset, C1)),否则只能返回obj
同样表示疑惑,看代码注释aprioriGen——应该是用来生成所有可能k+1维数据,但是L1 == L2就比较奇怪。。。

这里应该没有错误,输入为{0,1,2}和{1,2,3}的时候是一定还有一个输入为{0,1,3},{0,1,2}和{0,1,3}就能组合成{0,1,2,3}
