关于python：将字符串列表转换为列表列表，列表列表中的每个元素都作为字符串中的每个可迭代字母。

Convert list of strings into list of lists with each element in list of lists as each iterable letter in string. All in one line

与list of strings X：P＞＜／

1	x = ['foo', 'bar']

我怎么能在我下面一行？P＞＜／

1
2
3
4

y = []
for word in x:
y.append([n for n in word])
print y

导致：P＞＜／

1	[['f', 'o', 'o'], ['b', 'a', 'r']]

使用list和简单的列表理解：

1
2
3
4

>>> x = ['foo', 'bar']
>>> y = [list(word) for word in x]
>>> y
[['f', 'o', 'o'], ['b', 'a', 'r']]

或将map与list一起使用：

1
2
3

>>> y = map(list, x)
>>> y
[['f', 'o', 'o'], ['b', 'a', 'r']]

1 2	>>> map(list, ['foo', 'bar']) [['f', 'o', 'o'], ['b', 'a', 'r']]

您可以从列表理解中的每个字符串创建一个list。

1
2
3

>>> x = ['foo', 'bar']
>>> [list(i) for i in x]
[['f', 'o', 'o'], ['b', 'a', 'r']]
