我正在使用 tkinter 來制作簡單的 GUI，我想讓它變得太簡單和酷所以我想這個標簽 ********** 被填充在屏幕上但是沒有像fill在網格中這樣的選項打包，所以我正在尋找替代品。這是代碼：import tkinterimport osdef submit():    os.chdir("/home/samip/forms")    with open(f'{user_val.get()}.txt', 'w') as file:        file.write(f'''Person Details        User: {user_val.get()}        Age: {age_val.get()}        Address: {address_val.get()}        ''')        quit()root = tkinter.Tk()root.geometry("400x200")root.maxsize(400, 200)root.minsize(400, 200)root.title("Mars form")lab = tkinter.Label(text="Mars Form", font=("Arial", 15, "bold"), bg="orange", fg="white", padx=10)lab.grid()user = tkinter.Label(text="Name:")age = tkinter.Label(text="Age:")address = tkinter.Label(text="Address:")user.grid()age.grid()address.grid()user_val = tkinter.StringVar()age_val = tkinter.StringVar()address_val = tkinter.StringVar()user_val_entry = tkinter.Entry(root, textvariable=user_val)age_val_entry = tkinter.Entry(root, textvariable=age_val)address_val_entry = tkinter.Entry(root, textvariable=address_val)user_val_entry.grid(row=1, column=1)age_val_entry.grid(row=2, column=1)address_val_entry.grid(row=3, column=1)tkinter.Button(root, text="Submit", command=submit).grid(row=4, column=1)root.mainloop() 我要填寫的標簽在第 24 行。
