RDD map + sortByKey - 错误理解列表python

Question

He Guys。

当我做这样的事情时，我一直收到错误：

RDD = [(0, [1,2,3], 2),(1, [2,3,4], 4),(2, [4,5,6], 6),(3, [6,7,8], 8)]
Dados = [4,5,6]

TesteEuclediana = RDD.map(lambda x: (x[0],
                                     [math.sqrt((x[1][i][1]- Dados[i])^2) for i in range (0, int(len(Dados)))],
                                     x[2])
                         ).sortByKey()

我发现了这个错误：

AttributeError: 'list' object has no attribute 'map'
