I am trying to match following string in Python.

100xyz, inc. provides information services aaaaaaaaaaaaaaaaaaaaa.

I expect the matching result as follows:

inc provide information services

I used [a-z]{3,15} and got

xyz inc provide information services aaaaaaaaaaaaaaa aaaaaa

How can I achieve the result I want?

`re.findall(r'\b[a-z]{3,15}\b', s)` – Wiktor Stribiżew Apr 11 '18 at 19:52
@WiktorStribiżew How to revise your code to exclude words including three consecutive characters, such as 'aaa'? – Houhouhia Apr 11 '18 at 20:54
`[x.group() for x in re.finditer(r'\b(?![a-z]*([a-z])\1{2})[a-z]{3,15}\b', s)]` – Wiktor Stribiżew Apr 11 '18 at 22:23
