You can use

re.sub(r'([^\W\d_][.,])(\s+)', r'\1<break></break>\2', text)

See the regex demo .

Details :

• ([^\W\d_][.,]) - Group 1 ( \1 ): any letter and then a . or ,
• (\s+) - Group 2 ( \2 ): one or more whitespace chars.

See the Python demo :

import re
text = "hello this is me,<break></break> and only me.<break></break> be carefull from 911. "
print(re.sub(r'([^\W\d_][.,])(\s+)', r'\1<break></break>\2', text))
# => hello this is me,<break></break> and only me.<break></break> be carefull from 911.
