python 正则表达式截取一段字符串

标题可能表达的不清楚，看下面的例子。

比如有一段字符串和一个名字列表：

string = "David comes from china. he loves watching tv shows. Tom is an american, he loves games. Rick blablabla"
names = ["David", "Tom", "Rick"]

想写个函数，要return的结果:

r = ["David comes from china. he loves watching tv shows.", "Tom is an american, he loves games.", "Rick blablabla"]

不一定非要用正则。

string = "David comes from china. he loves watching tv shows. Tom is an american, he loves games. Rick blablabla"
names = ["David", "Tom", "Rick"]

import re

print(re.split(r'(?<=\.)\s*(?=%s)' % '|'.join(names), string))
