在我的代码中，我只想让发送者的名字加粗。这意味着我只想让“User”和“Gpt-3.5-turbo”加粗。不知为何，由“User”发送的消息总是加粗。此外，如我附件的图片所示，“User”和“Gpt-3.5-turbo”之间没有换行，尽管在“User”和“Gpt-3.5-turbo”的第一条消息之间有空格。我尝试了许多命令来解决这个问题，但都没有成功。有人能帮我解决这两个问题吗？以下是我的代码：
import tkinter as tkfrom tkinter import ttkfrom datetime import datetimeimport openaiimport jsonimport requestshistory = []# Create a function to use ChatGPT 3.5 turbo to answer a question based on the promptdef get_answer_from_chatgpt(prompt, history): openai.api_key = "sk-xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx" print("Trying") messages = [ {"role": "system", "content": "You are a helpful assistant."} ] for sender, message in history: messages.append({"role": sender, "content": message}) try: stream = openai.chat.completions.create( model="gpt-3.5-turbo", messages=messages, stream=True, ) append_to_chat_log("Gpt-3.5-turbo") for chunk in stream: if chunk.choices[0].delta.content is not None: chunk = chunk.choices[0].delta.content append_to_chat_log(message=chunk) #history.append(("assistant", chunk)) append_to_chat_log(message="\n") #chat_log.insert("end",'\n\n') print("Streamig complete") except Exception as e: print(e) return "Sorry, an error occurred while processing your request."def append_to_chat_log(sender=None, message=None): chat_log.config(state=tk.NORMAL) if sender: chat_log.insert("end", f"{sender}\n\n", "sender") #chat_log.insert("end",'\n\n') if message: chat_log.insert("end", message) chat_log.tag_config("sender", font=('Arial', 12, 'bold')) chat_log.config(state=tk.DISABLED) chat_log.see("end") chat_log.update()def send_message(event=None): global history message = message_entry.get(1.0, "end-1c") message = message.strip() message_entry.delete(1.0, tk.END) message_entry.update() if not message: pass else: append_to_chat_log("User") append_to_chat_log(message) history.append(("user", message)) if len(history) >4: history = history[-4:] get_answer_from_chatgpt(message, history) print(history)root = tk.Tk()root.title("Chat")# Maximize the windowroot.attributes('-zoomed', True)chat_frame = tk.Frame(root)chat_frame.pack(expand=True, fill=tk.BOTH)chat_log = tk.Text(chat_frame, state='disabled', wrap='word', width=70, height=30, font=('Arial', 12), highlightthickness=0, borderwidth=0)chat_log.pack(side=tk.LEFT, padx=(500,0), pady=10)message_entry = tk.Text(root, padx=17, insertbackground='white', width=70, height=1, spacing1=20, spacing3=20, font=('Open Sans', 14))message_entry.pack(side=tk.LEFT, padx=(500, 0), pady=(0, 70)) # Adjust pady to move it slightly above the bottom#message_entry.insert(0, "Ask me anything...")message_entry.insert(1.0, "Ask me anything...")message_entry.mark_set("insert", "%d.%d" % (0,0))message_entry.bind("<Return>", send_message)#message_entry.bind("<Button-1>", click)root.mainloop()我尝试使用像chat_log.insert("end",'\n\n')和append_to_chat_log(message="\n")这样的命令在def get_answer_from_chatgpt(prompt, history):函数中，但似乎都不起作用。
回答：
用户的消息之所以加粗，是因为你在append_to_chat_log()函数中对message的调用有误，你需要像下面这样使用message选项：
def send_message(event=None): ... else: append_to_chat_log("User") # 记录发送者 append_to_chat_log(message=message) # 记录消息 ...要在消息之间添加换行符，你可以在GPT响应前后添加换行消息：
def get_answer_from_chatgpt(message, history): ... try: ... # 在响应前添加换行符 append_to_chat_log(message="\n\n") append_to_chat_log("Gpt-3.5-turbo") for chunk in stream: ... # 在响应后添加换行符 append_to_chat_log(message="\n\n") ... ...
