--SOLVED--我通过启用多行模式解决了我的问题,现在字符^和$完美地用于识别每个字符串的开头和结尾

我的代码:

import re
import test_regex


def regex_content(text_content, regex_dictionary):

#text_content = text_content.lower()
regex_matches = []

# Search sanitized text (markup removed) for DLP theme keywords
for key,value in regex_dictionary.items():

  # Get confiiguration settings
  min_matches = value.get('min_matches',1)
  risk = value.get('risk',1)
  enabled = value.get('enabled',False)
  regex_str = value.get('regex','')

  # Fast compute True/False hit for each DLP theme word
  if enabled:
    print "Searching for key : %s" % (key)
    my_regex = re.compile(value.get('regex'))
    hits = my_regex.findall(text_content)

    if len(hits) > 0:
      regex_matches.append((key, risk, …

为什么我无法使用堆栈的push()和pop()函数调用？以下是错误:

看来我的问题是当这个select语句返回null时(我正在尝试处理的情况 - 当它返回null时,我希望我的新值为-999).如果在找到null时出错,我怎么能这样做呢？

我已经阅读了有关此错误的所有其他SO帖子,但其中没有一个似乎解决了我的问题的根源.

错误非常简单 - 我的EXECUTE语句中的一个参数为null.大.但是,我在调用之前打印出构成我的EXECUTE语句的每个值,并且我可以清楚地看到没有值为null.

码:

                                            last_member_id int, dest_file text)
