Python列表与元组的异同详解

>>> foos = [0, 1, 2, 3, 4, 5, 6, 7, 8, 9]
>>> foos[0:10:2]
[0, 2, 4, 6, 8]
>>> bars = (0, 1, 2, 3, 4, 5, 6, 7, 8, 9)
>>> bars[1:10:2]
(1, 3, 5, 7, 9)

>>> foo = [2,3,1,9,4]
>>> foo.sort() # 排序
>>> foo.insert(5,10) # 插入
>>> foo.reverse() # 反转
>>> foo.extend([-1, -2]) # 扩展
>>> foo.remove(10) # 移除
>>> foo.pop() # 弹出最后一个元素
>>> foo.append(5) # 追加

>python -m timeit "[1,2,3,4,5]"
10000000 loops, best of 3: 0.123 usec per loop
>python -m timeit "(1,2,3,4,5)"
100000000 loops, best of 3: 0.0166 usec per loop

>>> foo = tuple(range(1000))
>>> bar = list(range(1000))
>>> foo.__sizeof__()
8024
>>> bar.__sizeof__()
9088

>>> foo = (1,(2,3))
>>> d = {foo: 1}
>>> bar = (1, [2,3]) # 非原子性tuple，因为元组中包含有不可哈希的list
>>> d = {bar: 1}
