元祖容器可雜湊
>>>hash((1,))
3430019387558
元祖中的元素不可直接修改
>>>tu = (1, 2, 3, [4])
>>>tu[-1].append(5)
>>>tu
(1, 2, 3, [4, 5])
>>>tu[0] = 6
TypeError: `tuple` object does not support item assignment
元祖可迭代
>>>from collections import Iterable
>>>isinstance(tuple(), Iterable)
True
查
>>>tu = (`a`, `b`, `c`, `d`)
>>>tu[0]
`a`
>>>tu[:2]
(`a`, `b`)
練習
列舉，列表，元祖的結合練習
>>> lst = [(`登陸`, `sign_in`), (`註冊`, `sign_up`)]
>>> for index, item in enumerate(lst, 1):
… index, item[0]
…
(1, `登陸`)
(2, `註冊`)
