How to select text using regular expression?

Question

Python

You need to get all the text that will begin with numbers, including subsequent paragraphs.
I would like to get the following result:

1 Contrary to popular belief, Lorem Ipsum is not simply random text.
     It has roots in a piece of classical Latin literature from 45 BC, making it over 2000 years old. 
  
  Richard McClintock, a Latin professor at Hampden-Sydney College in Virginia,
    looked up one of the more obscure Latin words,

  ...

2 Consectetur, from a Lorem Ipsum passage, and going through the 
  ...

N ...

The text itself looks like this:

    (The Extremes of Good and Evil) by Cicero, written in 45 BC.
