_x000D_ _x000D_ I wonder whether there is a shortcut to make a simple list out of list of lists in Python. I can do that in a for loop, but maybe there is some cool "one-liner"? I tried it with reduce, but I get an error. Code l = [[1, 2, 3], [4, 5, 6], [7], [8, 9]] reduce(lambda x, y: x.extend(y), l) Error message Traceback (most recent call last): File "", line 1, in File "", line 1, in AttributeError: 'NoneType' object has no attribute 'extend'
