How to make specific words within word document bold

Question

I'm trying to get the words that are inside my api response, the message variable, that are all inside the document and make only them bold. I've tried in every way, even asking chatgpt for help to make these changes, however, I'm not succeeding.

My code:

import os
import shutil
from docx import Document
import requests
from senhaapi import API_KEY
import json
from docxtpl import DocxTemplate
import docx
from docx.shared import Pt
import re
from docx.oxml.ns import qn
from docx.oxml import OxmlElement
from docx.enum.text import WD_PARAGRAPH_ALIGNMENT

ans = read_multiple_choice(
    "Escolha a matéria da prova que será submetida",
    [{"label": "Português", "value": "portugues"},
     {"label": "Matemática", "value": "matematica"},
     {"label": "Geografia", "value": "geografia"},
     {"label": "História", "value": "historia"},
     {"label": "Física", "value": "fisica"},
     {"label": "Química", "value": "quimica"},
     {"label": "Literatura", "value": "Literatura"},
     {"label": "Inglês", "value": "ingles"},
     {"label": "Espanhol", "value": "espanhol"}, ],
)

if ans == "portugues":
    print("Processing the file for Português")  
    file_response = read_file("Enviar")
    file_name = file_response.name

    # Verificar se o arquivo tem a extensão .docx
    if not file_name.endswith(".docx"):
        display("A prova enviada deve estar no formato .docx", size='medium')
    else:
        script_dir = os.getcwd()
        destination_dir = os.path.join(script_dir, "foo/bar")
        os.makedirs(destination_dir, exist_ok=True)
        original_file_path = os.path.join(destination_dir, file_name)
        with open(original_file_path, "wb") as destination_file:
            shutil.copyfileobj(file_response.file, destination_file)

        # Abrir o documento com python-docx
        document = Document(original_file_path)

        texto_a_adicionar = "Teste"

        for paragraph in document.paragraphs:
            if not paragraph.text.strip():  # Verificar se o parágrafo está vazio
                run = paragraph.add_run(texto_a_adicionar)
                font = run.font
                font.size = Pt(8)
                break  # Parar após adicionar o texto



        for paragraph in document.paragraphs:
            for run in paragraph.runs:
                run.font.name = 'Arial'
                run.font.size = Pt(14)  # Tamanho da fonte em pontos
        questoes = {}
        questao_atual = None

        for paragraph in document.paragraphs:
            text = paragraph.text.strip()

            if text and text[0].isdigit() and text[1:2] == ")":
                if questao_atual is not None:
                    questoes[questao_numero] = questao_atual.strip()

                questao_numero = int(text.split(")", 1)[0])
                questao_atual = text.split(")", 1)[1]
            else:
                if questao_atual is not None:
                    questao_atual += " " + text

        if questao_atual is not None:
            questoes[questao_numero] = questao_atual.strip()

        keywords = []

        for question_number, question_content in questoes.items():
            # Split the question content into words
            words = re.findall(r'\w+', question_content)
            keywords.extend(words)  # Add words to the keywords list

        api_message = f"Verificar dentro de {', '.join(keywords)} quais são as palavras chaves ou verbos de comando, não mude o tempo verbal das palavras-chaves ou verbos de comando. Só me mostra na resposta apenas o que eu pedi, sem texto antes."

        headers = {"Authorization": f"Bearer {API_KEY}", "Content-Type": "application/json"}
        link = "https://api.openai.com/v1/chat/completions"

        id_modelo = "gpt-3.5-turbo"

        body_api = {
           "model": id_modelo,
           "temperature": 0.3,
           "messages": [{"role": "user", "content": api_message}]
        }

        body_api = json.dumps(body_api)

        request = requests.post(link, headers=headers, data=body_api)
        response = request.json()
        message = response["choices"][0]["message"]["content"]
        print(request)
        print(request.text)

        modified_file_path = os.path.join(destination_dir, "modified_" + file_name)
        document.save(modified_file_path)

else:
    display("Selecione uma opção válida", size='medium')

I tried this code and it didn't work:

for keyword in unique_keywords:
    for paragraph in document.paragraphs:
        for run in paragraph.runs:
            if keyword in run.text:
                new_text = run.text.replace(keyword, f'<w:b>{keyword}</w:b>')
                run.text = new_text


api_message = f"Verificar dentro de {', '.join(keywords)} quais são as palavras-chaves ou verbos de comando, não mude o tempo verbal das palavras-chaves ou verbos de comando. Só me mostra na resposta apenas o que eu pedi, sem texto antes."

for paragraph in document.paragraphs:
    for word in message.split():  # Divida a mensagem em palavras
        if word in paragraph.text:
            # Percorra as runs no parágrafo e destaque as palavras em negrito
            for run in paragraph.runs:
                if word in run.text:
                    run.bold = True

The display, file_responder, read_multiple_choice are from my work library

Thanks for the help
