Specific Python pattern for the string that can help to slice

I am looking for the pattern which helps me to slice a string. The string is something like this:

text = '1. first slice 2. second slice 3. slice number 3 4. the next one 5 that will not work but belong to no four 5. and this should be 5 and so one...'

I want to get this:

1. first slice
2. second slice
3. slice number 3
4. the next one 5 that will not work but belong to no four
5. and this should be 5 and so on...'

I hope you have get the idea. What I have examined till now is that I can use this:

import re

parts = re.findall("\d\\. \D+", text)

That works good until it encounter single number. I know that \D expression is non digit, and I tried to use:

parts = re.findall("\d\\. .+,text)

or

parts = re.findall("(\d\\.).*,text)

and many others but I cant find the proper one.

I will be greatful for your help.
