python中tuple函数

 

tuple函数将可迭代对象转化为元组。

1、

>>> tuple("abcde")
('a', 'b', 'c', 'd', 'e')
>>> a = tuple("abcde")   ## 字符串作为可迭代对象，将字符串转化为元组
>>> a
('a', 'b', 'c', 'd', 'e')
>>> type(a)
<class 'tuple'>
>>> b = ["aa","bb","cc","dd","ee"]
>>> type(b)
<class 'list'>
>>> c = tuple(b)   ## 列表最为可迭代对象，将列表转化为元组
>>> c
('aa', 'bb', 'cc', 'dd', 'ee')
>>> type(c)
<class 'tuple'>
