I have text like:

"ababbabbba"

I want to extract the characters as a list between a. For the above text, I am expecting output like:

['aba', 'abba', 'abbba']

I have used:

re.split(r'a(.*?)a', data)[1:-1]

But it doesn't work.

  • Why not something like: ['a' + t + 'a' for t in data.split('a')][1:-1] – Eric Marchand Dec 07 '21 at 17:07

If you are willing to use findall instead of split this works.

import re

s = "ababbabbba"

print(re.findall(r'(?=(a[^a]+a))',s))

prints:

['aba', 'abba', 'abbba']
