Splitting on regex without removing delimiters

So, I would like to split this text into sentences.

s = "You! Are you Tom? I am Danny."

so I get:

["You!", "Are you Tom?", "I am Danny."]

That is I want to split the text by the regex '[.!\?]' without removing the delimiters. What is the most pythonic way to achieve this in python?

I am aware of these questions:

JS string.split() without removing the delimiters

Python split() without removing the delimiter

But my problem has various delimiters (.?!) which complicates the problem.
