flatten_list = [x for sub_matrix inmatrix for row in sub_matrix for x in row]使用循环，平面化过程如下：flatten_list = []for sub_matrix in matrix:for row in sub_matrix:for x in row:flatten_list.append(x)列表式很酷，但可读的代码更酷。不要试图总是让自己使用列表式，即使这样做可能...

Flatten Nested List Iterator Flatten Nested List Iterator Given a nested list of integers, implement an iterator to flatten it. Each element is either
Given a nested list of integers, implement an iterator to flatten it. Each element is either an integer, or a list -- whose elements may also be integers or other lists. Example 1: Input: [[1,1],2,[1,1]] Output: [1,1,2,1,1] ...
