accessing/modifying Table of contents of a docx through python

Question

I need to change the font style of TOC content in the MS-Word document. This I want to do automatically through a python script.

I am able to access the TOC table, I can iterate over that as well .. but not able to access the font and size of the contents. My code is written in Python. Can someone please help. I want to change the font/size to a particular font / size.

Please help on how to do this : Here is my code :

from pydoc import doc
from docx.api import Document
from docx import Document
from docx.shared import Pt
from docx.shared import Inches
from datetime import date
from docx.enum.text import WD_PARAGRAPH_ALIGNMENT
from docx.oxml import OxmlElement, ns
from docx.oxml.shared import OxmlElement # Necessary Import
from docx.oxml.shared import qn
from docx.oxml.ns import qn
from docx.text.paragraph import Paragraph
from docx.enum.text import WD_ALIGN_PARAGRAPH
from docx.enum.style import WD_STYLE_TYPE
from docx2python import docx2python
from docx.opc.constants import RELATIONSHIP_TYPE as RT
from pathlib import Path
import diff_match_patch
from docx.enum.text import WD_BREAK
from docx.text.run import Run
from docx.oxml.text.run import CT_R
from docx.enum.style import WD_STYLE
import re
import mmap
import win32com.client
import inspect, os
import calendar
import tkinter as tk
from tkinter import filedialog
import time
import lxml
from calendar import month_name
from docx.enum.text import WD_COLOR_INDEX
from docx.enum.text import WD_LINE_SPACING
from docx.shared import RGBColor
import docx

root = tk.Tk()
root.withdraw()

file = filedialog.askopenfilename()
filepath = os.path.dirname(os.path.abspath(file))
document = Document(file)

def tocM():
    body_elements = document._body._body
    rs = body_elements.xpath('.//w:r')
    table_of_content = [r for r in rs if r.style == "Hyperlink"]
    for i in table_of_content:
        print("1111");
        print(i.text)
        print(i)
        print("2222");
    return;


tocM()

I have attached the snapshot of the docx file on which I am working. Please help.
