How do I format markdown chatgpt response in tkinter frame python?

题意：怎样在Tkinter框架中使用Python来格式化Markdown格式的ChatGPT响应？

问题背景：

Chatgpt sometimes responds in markdown language. Sometimes the respond contains ** ** which means the text in between should be bold and ### text ### which means that text is a heading. I want to format this correctly and display it properly in tkinter. If it's bold or a heading, it should be formatted to bold or to a heading in tkintter. How to do this?

ChatGPT有时会以Markdown语言回应。有时回应中包含** **，这表示中间的文本应该是粗体的；而### text ###则表示该文本是一个标题。我想在Tkinter中正确地格式化并显示这些文本。如果它是粗体或标题，则应该在Tkinter中以粗体或标题的形式显示。如何做到这一点？

My code:

import tkinter as tk

history = []
# Create a function to use ChatGPT 3.5 turbo to answer a question based on the prompt
def get_answer_from_chatgpt(prompt, historyxx):
    global history
 
    openai.api_key = "xxxxxxx"
    append_to_chat_log(message="\n\n\n")
    append_to_chat_log("Chatgpt")
 
    print("Trying")
 
    messages = [
            {"role": "user", "content": prompt}
        ]
 
    try:
        stream = openai.chat.completions.create(
            model="gpt-3.5-turbo",

        append_to_chat_log(message="\n\n\n")
        print("Streaming complete")

        print(e)
        return "Sorry, an error occurred while processing your request."
