016序列

sorted()

sum()

reversed()

>>> numbers = (1,5,7,646,-56)
>>> reversed(numbers)
<reversed object at 0x000001D2620DE640>
>>> list(reversed(numbers))
[-56, 646, 7, 5, 1]

enumerate()枚举

>>> list(enumerate(numbers))
[(0, 1), (1, 5), (2, 7), (3, 646), (4, -56)]

zip（）两组压缩

>>> a = [1,2,3,4,5,6,7,8]
>>> b = [4,5,6,7,8]
>>> list(zip(a,b))
[(1, 4), (2, 5), (3, 6), (4, 7), (5, 8)]
