This is a college enquiry chatbot, I want to get users name and display in the chat window.

On the output window, I want the student's name instead of "Student". I have added only some code that I think is important. If you want full code comment below, I'll edit the question

def _on_enter_pressed(self, event):
    msg = self.msg_entry.get()
    self._insert_message(msg,"Student")
    
def _insert_message(self, msg, sender):
    if not msg:
        return
    
    self.msg_entry.delete(0, END)
    msg1 = f"{sender}: {msg}\n\n"
    self.text_widget.configure(state=NORMAL)
    self.text_widget.insert(END, msg1)
    self.text_widget.configure(state=DISABLED)
    
    msg2 = f"{bot_name}: {get_response(msg)}\n\n"
    self.text_widget.configure(state=NORMAL)
    self.text_widget.insert(END, msg2)
    self.text_widget.configure(state=DISABLED)
    
    self.text_widget.see(END)

CodePudding user response：

As the two other commentors mention:

studentName = self.student_entry.get()
self._insert_message(msg,studentName)

where student_entry is a tk.Entry(). But you could get studentName from anywhere else in the code.

CodePudding user response：

I'm not sure what kind of user interface you want to have, but one way to get the user's input in by using one of the simple dialogs included in tkinter. Below is a modified version of you code with the changes needed to add a Button to invoke one, get the string entered, and use it. I've indicated where the changes were made with all caps # ADDED and # CHANGED comments.
