我的文字如下（底部）。这是足球的比赛数据。我正在根据本季度的两个参数，季度和分钟来创建一个函数来从这个文本中获取数据。因此，如果函数被传递quarter=q2, time=10，我必须从头开始抓取所有文本，直到我在第二季度记录10分钟时播放的游戏。问题是第二季度可能没有时间戳可以找到10分钟。所以正则表达式会一直持续到第三季度或第四季度...另一个问题是，如果第二季度没有时间戳10，那么正确的行为是抓住所有文本，直到时间戳为9，然后是8，等等
我可以通过将游戏数据分成四个文本变量来实现这一点，每个季度一个（第四季度将包括加班）。然后我可以制作一个正则表达式，在正确的时间找到给定四分之一的游戏，并将其粘贴在一个循环中，这将继续调整时间戳直到匹配。然后我可以将所有前几个季度的文本（例如，如果我在第2季的文本变量中搜索，只是第1季度）附加到我在指定季度找到的匹配项。
有没有更好的方法来实现这一点，“高效”，正则表达式？

答案 0 :(得分：2)
这绝对不是最好的方法，但是如果你确定数据会以这种格式出现，那么这个（草率的）代码应该可以工作：
>>> commentary = #your commentary text
>>>
>>> # Returns the string up to the timestamp.
... # quarter is an int, 1-4, time is int, 0-15.
... def getPlayByPlay(commentary, quarter, time):
... reString = r'\w\w Quarter' #1st Quarter, 2nd Quarter, etc.
... quarterDex = re.search(str(quarter) + reString, commentary).start()
... endQuarterDex = 0
... if quarter == 4:
... endQuarterDex = len(commentary)
... else:
... endQuarterDex = re.search(str(quarter + 1) + reString, commentary).start()
... for match in re.finditer(r'at \d\d:\d\d', commentary[quarterDex:endQuarterDex]):
... matchTime = int(match.group(0)[3:5])
... print matchTime
... if matchTime < time:
... return commentary[:quarterDex + match.start()]
... return commentary[:endQuarterDex]
>>> getPlayByPlay(commentary, 1, 3)
'\n1st Quarter Play by Play ... End of 1st Quarter \n'
>>> getPlayByPlay(commentary, 1, 13)
'\n1st Quarter Play by Play ... 02:12 Memph FG\n Marshall '
>>> getPlayByPlay(commentary, 4, 0)
gives the whole string
如您所见，没有错误检查，这完全取决于我在这个具体示例中找到的模式。如果quarter不是1到4之间的int或者时间不是而且int介于0和15之间，则会导致崩溃或返回错误。请确保您注意到time是int（否）小数） - 如有必要，您可以进行更复杂的分析。希望它有用！
