I'm trying to parse lines like "THIS. THAT..OTHER " so that `"THIS. THAT."` is found. There can be more that one <word><dot> separated by a space except no space after the last one. Based on the initial feedback, I've added more example lines to the lines array below.
My current results are:
```
re.compile('\\s?(?P<name>(?:\\w+\\.\\s(?=[\\.\\s]))+)', re.VERBOSE)
REGEX FAILED: [THIS. THAT..OTHER
```
Here is the current code. I have tried several different regexes trying to find one that seeks the blank space after a dot for all but the last word/dot combination.
```
lines = [
'THIS. THAT..OTHER ',
'THIS. THAT. ANOTHER..OTHER ',
'THIS..OTHER ',
]
pat = re.compile(r"\s?(?P<name>(?:\w+\.\s(?=[\.\s]))+)", re.VERBOSE)
print(pat)
for line in lines:
x = pat.match(line)
if x:
if hasattr(x, 'groupdict'):
print(x.groupdict())
else:
print(x.groups())
else:
print("REGEX FAILED: [{}]".format(line))
```

Python Regex to parse multiple "word. word. word."

I'm trying to parse lines like "THIS. THAT..OTHER    " so that "THIS. THAT." is found.  

My current results are:
```
re.compile('\\s?(?P<name>(?:\\w+\\.\\s(?=[\\.\\s]))+)', re.VERBOSE)
REGEX FAILED: [THIS. THAT..OTHER 
```

Here is the current code.  I have tried several different regexes trying to find one that seeks the blank space after a dot for all but the last word/dot combination.   

```
lines = [
    'THIS. THAT..OTHER                  ',
]

pat = re.compile(r"\s?(?P<name>(?:\w+\.\s(?=[\.\s]))+)", re.VERBOSE)

print(pat)

for line in lines:
    x = pat.match(line)

    # print(x)

    if x:

        if hasattr(x, 'groupdict'):
            print(x.groupdict())
        else:
            print(x.groups())
    else:
        print("REGEX FAILED: [{}]".format(line))
```
