Adding a paragraph on page 2 of a docx through python script

Question

I want to add a small paragraph to my docx file. This I want to do automatically through python script. But when I run my script, it adds it in the last page, instead of the 2nd page .

Can someone please guide me how to correct it :

Here is my code :

def addPage():
    p = 1
    for paragraph in document.paragraphs:
        for run in paragraph.runs:
            if 'lastRenderedPageBreak' in run._element.xml:
                p+=1
                if p==2:
                   document.add_paragraph('hello world.')
