分割字符串數組成字符

Question

我試圖字符串數組從每個字符串分割成字符的2D陣列的2D陣列

lines = ['abc','123','ggg'] 
list(lines) 
print lines 
#['abc','123','ggg'] 
#nothing changed 
#I want [['a','b','c'],['1','2','3'] etc.. 

而用一個字符串，

print list('lala') 
#['l', 'a', 'l', 'a'] 
#It works! 

感謝

使用map()：

>>> map(list, lines) 
[['a', 'b', 'c'], ['1', '2', '3'], ['g', 'g', 'g']] 

或者用list comprehension：

>>> [list(line) for line in lines] 
[['a', 'b', 'c'], ['1', '2', '3'], ['g', 'g', 'g']]
