我试图从文本中获得LOCATION 03-ED-0999-VAR(第二场比赛)。有没有一种方法可以在python中指定我们想要第二个，第三个或第n个匹配?现在，我有以下代码:

location1 = re.search('LOCATION s+S+', text)
不要用re.search()，可以试试用re.findall()。这将以列表的形式为您提供所有匹配项，您可以选择您喜欢的任何一个，甚至可以计算您获得了多少个。
location1 = re.findall("LOCATION s+S+", text)
print(len(location1)) # To print how many matches there are
print(location1[1]) # To print second match
