1、拆箱
>>> a, b, c = 1, 2, 3
>>> a, b, c
(1, 2, 3)
>>> a, b, c = [1, 2, 3]
>>> a, b, c
(1, 2, 3)
>>> a,...range(3))
>>> a, b, c
(1, 3, 5)
>>> a, (b, c), d = [1, (2, 3), 4]
>>> a
1
>>> b
2
>>> c
3
>>> d
4
2、使用拆箱进行变量交换...>>> a, b = 1, 2
>>> a, b = b, a
>>> a, b
(2, 1)
3、扩展的拆箱(Python 3支持)
>>> a, *b, c = [1, 2, 3, 4, ...(1, "a"), (2, "b"), (3, "c")]
>>> zip(*z)
[(1, 2, 3), ("a", "b", "c")]
14、使用zip分组相邻列表项
>>> a = [1...40、使用C风格的大括号代替Python缩进来表示作用域
>>> from __future__ import braces
