python3 list、tuple(元组)、str之间的相互转换

list()方法是把字符串str或元组转成数组
tuple()方法是把字符串str或数组转成元组

>>> s = "xxxxx"
>>> list(s)
['x', 'x', 'x', 'x', 'x']
>>> tuple(s)
('x', 'x', 'x', 'x', 'x')
>>> tuple(list(s))
('x', 'x', 'x', 'x', 'x')
>>> list(tuple(s))
['x', 'x', 'x', 'x', 'x']

列表和元组转换为字符串则必须依靠join函数

>>> "".join(tuple(s))
'xxxxx'
>>> "".join(list(s))
'xxxxx'
>>> str(tuple(s))
"('x', 'x', 'x', 'x', 'x')"#要是使用sublime text 3插件sublimeREPl，是不会显示外层的双引号的。上面同理。
