使用numpy在矩阵中查找路径

Question

我有aplhabets列表，我用numpy比较它们 比如在文件1中我有

File 1

a,b,c

c,d,f

File 2

c,d,f

我将file1的每个元素与文件2进行比较，并生成类似

的矩阵

0 0 0 (a compares with all of aplhabets in file b)

0 0 0(bcompares with all of aplhabets in file b)

0 0 1(c compares with all of aplhabets in file b)


1 0 0(c compares with all of aplhabets in file b)

0 1 0(d compares with all of aplhabets in file b)

0 0 1(f compares with all of aplhabets in file b)

现在我必须证明从a到d的路径我怎样才能找到路径？
