有没有办法加入子列表

Question

字符串列表，我有以下子列表：

[['a', 'b'], ['c', 'd'], ['e', 'f'], ['g']] 

但有可能投身于子列表清单？

[['ab'], ['cd'], ['ef'], ['g']] 

Answer 1

>>> L = [['a', 'b'], ['c', 'd'], ['e', 'f'], ['g']] 
>>> [[''.join(x)] for x in L] 
[['ab'], ['cd'], ['ef'], ['g']] 

Answer 2

此外，您还可以使用地图它

>>> L = [['a', 'b'], ['c', 'd'], ['e', 'f'], ['g']] 
>>> map(lambda x: [''.join(x)], L) 
[['ab'], ['cd'], ['ef'], ['g']]
