[已解决]关于字符串、列表、及元组的相关问题。

用心挽留python

问题一：内置的BIF中有没有可以反向排列所输入的字符转的？

问题二：
输入字符串
>>> x='abcdef'
>>> x= list(x)
>>> x
['a', 'b', 'c', 'd', 'e', 'f']

>>> x= str(x)
>>> x
"['a', 'b', 'c', 'd', 'e', 'f']"

>>> x=tuple(x)
>>> x
('[', "'", 'a', "'", ',', ' ', "'", 'b', "'", ',', ' ', "'", 'c', "'", ',', ' ', "'", 'd', "'", ',', ' ', "'", 'e', "'", ',', ' ', "'", 'f', "'", ']')

相互转化越来越复杂，这是怎么回事，有没有好的解决方法？萌新求助！万分感谢！

>>> a = 'abcdef'
>>> a = list(a)
>>> a
['a', 'b', 'c', 'd', 'e', 'f']
>>> a = ''.join(a)
>>> a = list(a)
>>> print(*a)
a b c d e f
>>> a = 'abcdef'
>>> a = tuple(a)
>>> a
('a', 'b', 'c', 'd', 'e', 'f')
>>> print(*a)
a b c d e f
>>> a = ''.join(a)
>>> a
'abcdef'

你是这个意思吗？

>>> x='abcdef'
>>> x= list(x)
>>> x
['a', 'b', 'c', 'd', 'e', 'f']
>>> ''.join(x)
'abcdef'
