Python-將字符串分成列表列表中的單詞

Question

我有以下列表列表（）：

[[u' why not giving me service'], [u' option to'], [u' removing an'], [u' verify name and '], [u' my credit card'], [u' credit card'], [u' theres something on my visa']]

我有以下問題：首先，這些u'出現在每個子列表的前面嗎？ 其次，如何將子列表分成單獨的單詞，即具有以下內容：

 [[why, not, giving, me, service], [option, to], [removing, an], [verify, name, and], [my, credit, card], [credit, card], [theres, something, on, my, visa]]

我已經嘗試了split函數，但是收到以下錯誤消息： AttributeError: 'list' object has no attribute 'split' 。

Answer 1

使用str.split()函數：

l = [[u' why not giving me service'], [u' option to'], [u' removing an'], [u' verify name and '], [u' my credit card'], [u' credit card'], [u' theres something on my visa']]

result = [_[0].split() for _ in l]
print(result)

輸出：

[['why', 'not', 'giving', 'me', 'service'], ['option', 'to'], ['removing', 'an'], ['verify', 'name', 'and'], ['my', 'credit', 'card'], ['credit', 'card'], ['theres', 'something', 'on', 'my', 'visa']]

Answer 2

碼：

list_1 = [[u' why not giving me service'], [u' option to'], [u' removing an'], [u' verify name and '], [u' my credit card'], [u' credit card'], [u' theres something on my visa']]
res = []
for list in list_1:
    res.append(str(list[0]).split())

print res

輸出：

[['why', 'not', 'giving', 'me', 'service'], ['option', 'to'], ['removing', 'an'], ['verify', 'name', 'and'], ['my', 'credit', 'card'], ['credit', 'card'], ['theres', 'something', 'on', 'my', 'visa']]

你代表unicode，我希望這能回答你的問題

Answer 3

x=[[u' why not giving me service'], [u' option to'], [u' removing an'], [u' verify name and '], [u' my credit card'], [u' credit card'], [u' theres something on my visa']]
[[y.split() for y in m] for m in x]

這是它的輸出：

In [3]: [[y.split() for y in m] for m in x]
Out[3]: 
[[[u'why', u'not', u'giving', u'me', u'service']],
 [[u'option', u'to']],
 [[u'removing', u'an']],
 [[u'verify', u'name', u'and']],
 [[u'my', u'credit', u'card']],
 [[u'credit', u'card']],
 [[u'theres', u'something', u'on', u'my', u'visa']]]
