text = "Trondheim is a small city with a university and 140000 inhabitants. Its central bus systems has 42 bus lines, serving 590 stations, with 1900 (departures per) day in average. T h a t gives approximately 60000 scheduled bus station passings per day, which is somehow represented in the route data base. The starting point is to automate the function (Garry Weber, 2005) of a route information agent."
print re.findall(r"([^.]*?\(.+ [0-9]+\)[^.]*\.)",text)
我使用上面的代码在其中引用带有引文的句子。如你所见，最后一句包含引文（Garry Weber，2005）。
但我得到了这个结果：
[' Its central bus systems has 42 bus lines, serving 590 stations, with 1900 (departures per) day in average. T h a t gives approximately 60000 scheduled bus station passings per day, which is somehow represented in the route data base. The starting point is to automate the function (Garry Weber, 2005) of a route information agent.']
结果应该是仅包含引用的句子，如下所示：
起点是自动化路线信息代理的功能（Garry Weber，2005）。
我猜这个问题是由括号内的文字引起的，你可以在它包含的第二行看到（离开），我的代码的任何解决方案？
