我正在尝试实现Naive Gauss并在执行时获得不受支持的操作数类型错误.输出:

  execfile(filename, namespace)
  File "/media/zax/MYLINUXLIVE/A0N-.py", line 26, in <module>
    print Naive_Gauss([[2,3],[4,5]],[[6],[7]])
  File "/media/zax/MYLINUXLIVE/A0N-.py", line 20, in Naive_Gauss
    b[row] = b[row]-xmult*b[column]
TypeError: unsupported operand type(s) for -: 'list' and 'list'
>>>   

这是代码

def Naive_Gauss(Array,b):
    n = len(Array)

    for column in xrange(n-1):
        for row in xrange(column+1, n):
            xmult = Array[row][column] / Array[column][column]
            Array[row][column] = xmult
            #print Array[row][col]
            for col in xrange(0, n):
                Array[row][col] = Array[row][col] - xmult*Array[column][col]
            b[row] = b[row]-xmult*b[column]


    print Array
    print b

print Naive_Gauss([[2,3],[4,5]],[[6],[7]])
