As @ArtOfCode mentioned, it is not fully clear what you are trying to match.
From the first line in your post, you are trying to extract `THIS. THAT.` out of `THIS. THAT..OTHER `. The following regex achieves it:
`
>>> re.search('([A-Z]+\.\s?)+', 'THIS. THAT..OTHER ')
<re.Match object; span=(0, 11), match='THIS. THAT.'>
`
However, from your title and your last paragraph, it sounds more like you are trying to extract `THIS. THAT.` out of `THIS. THAT. OTHER.`, with potential white spaces at the end. In that case, this other regex can be of use:
`
>>> re.search('(\s?[A-Z]+\.)+(?=(\s+[A-Z]+\.?\s?)\Z)', 'THIS. THAT. OTHER. ')
<re.Match object; span=(0, 11), match='THIS. THAT.'>
`
If none of these expressions are what you are looking for, please clarify your question.
