拼合列表时出现非序列错误

Question

我有以下列表（在计算完其他函数之后生成）：

[1, 0, 2]
[1, 0, 2]
[0]
[1]
[2]
[1, 0, 2]
[0]
[1]
[2]
[1, 2, 0]
[0, 1]
[2]
[0, 2, 1]
[0, 1, 2]
[0, 1, 2]
[2, 0]
[1]
[2, 0]
[1]

我想生成一个扁平化列表[1, 0, 2, 1, 0, 2, 0, 1, 2, 1, 0, 2, 0, 1, 2, 1, 2, 0, 0, 1, 2, 2, ....]。元素可以重复，但结尾的长度不相等（0可能是10，1可能是30，...）。

我运行print([list(i) for i in componentVisited])

我收到以下错误：

TypeError: iteration over non-sequence
