python - 构建在字符串中搜索不同子字符串的 Python 代码的最佳方式

Question

自从尝试学习 python 以来，我正在使用 BeautifulSoup 作为我的第一个项目制作足球评论刮板。

基本上对于每个目标陈述，它可能是一个目标、一个乌龙球或一个点球，我需要将这些单独记录在我的数据库中。

出现的问题是有时目标语句包含“罚球区”或“罚球区”，因此我需要将这些情况记录为进球而不是罚球。

我用大量嵌套语句模拟了一些东西，但它很脏。

所以最初我有一些类似的东西

if goal in statement:
   if 'own goal' in statement:
      {record own goal in db}
   elif 'penalty' in statement:
      if not 'penalty area' in statement:
          if not 'penalty box' in statement:
              {record penalty in db}
   else:
      {record goal in db}

我只是一起嘲笑它，因为我没有代码。这是实现这一目标的唯一方法吗？

Answer 1

To clean it up, you can maybe combine some logical statements, but apart from that I don't see much improvement.

if 'goal' in statement:
    if 'own goal' in statement:
        {record own goal}
    elif 'penalty' in statement and not('penalty area' in statement) and not('penalty box' in statement):
        {record penalty}
    else:
        {record goal}

Answer 2

也许这样更好：

   if 'goal' in statement:
       if 'own goal' in statement:
           {record own goal in db}
       elif not('penalty area' in statement or 'penalty box' in statement):
           {record goal in db}
       elif 'penalty' in statement:
           {record penalty in db}
       else:
           {record goal in db}
