1 行 Python 代码能干哪些事，这 13 个你知道吗？

python -c "import this""""The Zen of Python, by Tim Peters
Beautiful is better than ugly.Explicit is better than implicit.Simple is better than complex.Complex is better than complicated.Flat is better than nested.Sparse is better than dense.Readability counts.Special cases aren t special enough to break the rules.Although practicality beats purity.Errors should never pass silently.Unless explicitly silenced.In the face of ambiguity, refuse the temptation to guess.There should be one-- and preferably only one --obvious way to do it.Although that way may not be obvious at first unless you re Dutch.Now is better than never.Although never is often better than *right* now.If the implementation is hard to explain, it s a bad idea.If the implementation is easy to explain, it may be a good idea.Namespaces are one honking great idea -- let s do more of those!"""

...11. 一行代码实现数组的 flatten 功能: 将多维数组转化为一维

flatten = lambda x: [y for l in x for y in flatten(l)] if isinstance(x, list) else [x]12. 一行代码实现 list, 有点类似与上个功能的反功能

array = lambda x: [x[i:i+3] for i in range(0, len(x), 3)]

print(sum(map(int, str(2**1000))))
