Question

我有一个tkinter gui。我有写到文件随机数的按钮。我想保持一个单独的窗口打开，该窗口记录所有正在写入文件的数据。因为它不会让我发布带有这么少描述的太多代码，所以这样做的目的是要使我警觉，而我按随机按钮几次是以前的描述，而没有打开文本文件。为了澄清起见，这只是代码的一部分。它有更多的窗口和随机功能，我在操作gui时还是很警惕。

    random1min_info = random1min.get()

# function to write entry to file

    with open("C:/random1.txt", 'r') as myfile:
        text = myfile.read()
    with open("C:/write in 1.txt", "a") as myfile2:
      myfile2.write(text + random1min_info +"," + random1max_info + ")// a=min, b=max" + "\n")

    Label(random1window, text = "random1 min * ").grid(row=1, column=1) 
    random1min_entry = Entry(random1window, textvariable = random1min)
    random1min_entry.grid(row=2, column=1)

    random1max_entry = Entry(random1window, textvariable = random1max)
    random1max_entry.grid(row=4, column=1) 

    Label(random1window, text = "").grid(row=5, column=1) 
    Button(random1window, text = "savedata", width = 10, height = 1, command = savedata).grid(row=6, column=1) 
    Label(random1window, text = "").grid(row=7, column=1) 
    Button(random1window, text = "write function", width = 10, height = 1, command = random1).grid(row=8, column=1) 

    def clearentries():
        random1min_entry.delete(0, END)
        random1max_entry.delete(0, END)

    Button(random1window, text = "clear entries", width = 10, height = 1, command = clearentries).grid(row=20, column=1) 



Button(root, text = "random1", width = 10, height = 4, command = random1entry).grid(row=9, column=4)





menu = Menu(root)
root.config(menu=menu)

file = Menu(menu)


file.add_command(label = 'Exit', command = lambda:exit())






root.mainloop()
