python - 如何停止 for 循环并使其进一步运行？

Question

我是Python新手。我希望你能帮助我;)

我有一个数据:

[('Senators', 'NNS'), ('and', 'CC'), ('a', 'DT'), ('good', 'JJ'), ('teacher', 'NN'),
  ('believes', 'VBZ'), ('in', 'IN'), ('the', 'DT'), ('possibilities', 'NNS'), ('of',
   'IN'), 
  ('every', 'DT'), ('boy', 'NN'), ('and', 'CC'), ('girl', 'NN'), ('.', '.'),
  ('The','DT'), 
  ('good', 'JJ'), ('teacher', 'NN'), ('sees', 'VBZ'), ('what', 'WP')......]

我想在列表中创建一个列表，其中包含每个句子，使其看起来像:

[ [('Senators', 'NNS'), ('and', 'CC'), ('a', 'DT'), ('good', 'JJ'), ('teacher', 'NN'),
  ('believes', 'VBZ'), ('in', 'IN'), ('the', 'DT'), ('possibilities', 'NNS'), ('of',
   'IN'), 
  ('every', 'DT'), ('boy', 'NN'), ('and', 'CC'), ('girl', 'NN')], [('The', 'DT'),
  ('good', 'JJ'), ('teacher', 'NN'), ('sees', 'VBZ'), ('what', 'WP')] ...]

但我不知道该怎么做:(我已经在 for 循环的帮助下尝试过

  for el in data:
     if el[0] != ('.' or '?' or '!'):   # finds only points((
     sentences.append(el)

当他找到一个点时我怎样才能停止循环？我怎样才能让它看得更远并写入新列表？

Answer 1

sentences = []
sentence = []

for word, code in data:
    sentence.append((word, code))
    if word in '.?!':
        sentences.append(sentence)
        sentence = []

如果您不想将要点包含在句子中:

sentences = []
sentence = []

for word, code in data:
    if word in '.?!':
        sentences.append(sentence)
        sentence = []
    else:
        sentence.append((word, code))
