Python:将多个列表连接成一个句子

Question

你好，我有多个列表。例如:

[u'This/ABC']
[u'is/ABC']
[u'not/ABC']
[u'even/ABC']
[u'close/ABC']
[u'to/ABC']
[u'funny/ABC']
[u'./ABC']

[u'O/ABC']
[u'noez/ABC']
[u'!/ABC']

我需要加入这个列表

This/ABC is/ABC not/ABC even/ABC close/ABC to/ABC funny/ABC ./ABC

O/ABC noez/ABC !/ABC

请问我该怎么做？是的，中间有空白!

Answer 1

如果你把它们都放在一个列表中，例如像这样:

a = [
    [u'This/ABC'],
    [u'is/ABC'],
    ...
]

您可以通过添加所有列表并对结果使用常规连接来获得结果:

result = ' '.join(sum(a, []))

---

在重新阅读问题几次之后，我想您也想要那条空行。这只是更多的相同。添加:

b = [
    [u'O/ABC'],
    [u'HAI/ABC'],
    ...
]

lines = [a, b]

result = '\n\n'.join([' '.join(sum(line, [])) for line in lines])
