relatively new to coding and currently I am playing with tkinter in python, I am using a text widget within a function and want to send the input from the text box to another function. My global variable says undefined at module level, so How could I make it defined at a module level if its within a function?
When I press the send email button I get this error message "NameError: name 'user_message_entry' is not defined"
Any suggestions? Many thanks!
minimum reproduction:
import tkinter as tk
root = tk.Tk()
root.geometry("500x500")
def send_email():
global user_message_entry
subject = ":)"
body = user_message_entry.get("1.0", "end")
message = f"subject: {subject}\n\n {body}"
print(message)
def feedback():
feedback_window = tk.Toplevel()
feedback_window.geometry("690x650")
message_frame = tk.Frame(feedback_window)
message_frame.grid(row=0, column=0, columnspan=3)
user_message_entry = tk.Text(message_frame, height=10, width=60)
user_message_entry.grid(row=0, column=0)
send_email_button = tk.Button(feedback_window, command=send_email,
height=20, width=20, bg="yellow", text="send email")
send_email_button.grid(row=1, column=0)
open_feedback_button = tk.Button(root, command=feedback, height=20, width=20, bg="yellow", text="open feedback window")
open_feedback_button.grid(row=1, column=0)
root.mainloop()
global user_message_entry
tofeedback()

still says undefined at module level. How could I sort this? – Kevin Nisbetsend_email()
