PYTHON REGEXP to replace recognized pattern with the pattern itself and the replacement?

Question

Text-

.1. This is just awesome.2. Google just ruined Apple.3. Apple ruined itself! pattern = (dot)(number)(dot)(singlespace)

Imagine you have 30 to 40 sentences with paragraph numbers in the above pattern. A <p> tag should be replaced behind THE PARAGRAPH NUMBER! USING re.sub()

I want the text to be:

</p> <p style="text-align: justify;">1. This is just awesome.</p> <p style="text-align: justify;">2. Google just ruined Apple.</p> <p style="text-align: justify;">3. Apple ruined itself!

This is what matching groups are for in regular expresssions.

What you want is something like this:

new_string = re.sub(r'\.(\d+\. )', '</p><p style="text-align: justify;">\\1', old_string)
