python - 找到一个被新行打断的长单词

Question

我正在尝试搜索单词列表，因此我生成了以下代码:

narrative = "Lasix 40 mg b.i.d., for three days along with potassium chloride slow release 20 mEq b.i.d. for three days, Motrin 400 mg q.8h"

meds_name_final_list = ["lasix", "potassium chloride slow release", ...]


def all_occurences(file, str):
    initial = 0
    while True:
        initial = file.find(str, initial)
        if initial == -1:
            return
        yield initial
        initial += len(str)
    offset = []
    for item in meds_name_final_list:
        number = list(all_occurences(narrative.lower(), item))
        offset.append(number)

期望的输出:正在搜索的单词语料库中的起始索引列表，例如:

offset = [[1], [3, 10], [5, 50].....]

此代码非常适用于不太长的单词，例如 antibiotics、emergency ward、insulin 等。但是，上面的函数不会检测到被新行间距打断的长单词。

所需词:氯化钾缓释

有什么解决这个问题的建议吗？

Answer 1

这个怎么样？

def all_occurences(file, str):
    initial = 0
    file = file.replace('\n', ' ')
    while True:
      initial = file.find(str, initial)
      if initial == -1: return
      yield initial
      initial += len(str)
