分享怎样把python 二维元组转成一个一维的python 列表?
a = [(4,2,3), (5, 9, 1), (7,8,9)]
想把a变成["4,2,3", "5, 9, 1", "7,8,9",]
先谢谢大家了。

In [3]: a = [(4,2,3), (5, 9, 1), (7,8,9)]
In [8]: b = [[str(y) for y in x] for x in a]
In [9]: b
Out[9]: [['4', '2', '3'], ['5', '9', '1'], ['7', '8', '9']]
In [10]: c = [",".join(z) for z in b]
In [11]: c
Out[11]: ['4,2,3', '5,9,1', '7,8,9']

>>> [','.join(map(str, t)) for t in a]
['4,2,3', '5,9,1', '7,8,9']
>>> [str(t)[1:-1] for t in a]
['4, 2, 3', '5, 9, 1', '7, 8, 9']
>>>
