从与CSV数据文件匹配中提取单词

Question

def fetch_data(document):
    with open('data_file.pickle', 'rb') as fp:
        datafile = pickle.load(fp)

    matched_word = []
    for data in datafile.splitlines():
        job_regex = r'[^a-zA-Z]'+data+r'[^a-zA-Z]'
        regular_expression = re.compile(job_regex, re.IGNORECASE)
        regex_result = re.search(regular_expression, document)
        if regex_result:
            matched_word.append(data)
    return matched_word

我想从datafile获取匹配数据到文档，但它返回空白列表。

Answer 1

根据您提供的信息，我相信您应该使用字边界，\ b，而不是：

job_regex = r'\b'+data+r'\b'
