Flattening a shallow list in Python




假设我有一个列表列表。

mylistOfLists = [[1, 2], [3, 4], [5, 6], [7, 8]]


python中获得此结果的最优雅方法是什么?

myCombinedList = [1, 2, 3, 4, 5, 6]


感谢您的任何建议!

最佳答案

myCombinedList = []
[myCombinedList.extend(inner) for inner in mylistOfLists]


要么:

import itertools
myCombinedIterable = itertools.chain.from_iterable(mylistOfLists)
myCombinedList = list(myCombinedIterable)
