Python 查找词序
我想检查文本中是否有单词序列,查看单词列表: word_list=“从不”、“不”、“购买”、“在这里”、“再次”、“更多”、“你好”、“不”、“将”、“桌子” text=“我愿意在这里购买更多” 预期产量:不会在这里购买更多 但不是: 威尔(重复序列) 不会(序列不完整) 我知道(用非常小的单词排序) 我的剧本:Python 查找词序,python,python-3.x,Python,Python 3.x,我想检查文本中是否有单词序列,查看单词列表: word_list=“从不”、“不”、“购买”、“在这里”、“再次”、“更多”、“你好”、“不”、“将”、“桌子” text=“我愿意在这里购买更多” 预期产量:不会在这里购买更多 但不是: 威尔(重复序列) 不会(序列不完整) 我知道(用非常小的单词排序) 我的剧本: word_list = "never", "not", "buy", "here", "ag

对于文本中的单词:
对于word\u列表中的word:
如果文本中有单词:
sequences.append(word)
计数器=+计数器
