Start heading 1 of existing docx in new page with python-docx

Question

In an existing word document, I want to start all the headings 1 beginning from the new page using #python-docx. I have tried the following code as below:

from docx import *

document=Document("document location")

sections=document.sections

for section in sections:

   document.add_page_break()

but the code is not working and it is adding additional page breaker where the existing heading 1 starting with new page. Please suggest any solution
