from tkinter import *

def save_d():
    files = open("mp3list.txt","a")
    files.write("title :\n")
    files.write("%s" % lists.get())
    files.write("appraisal :\n")
    files.write("%s\n" % appraisal.get())
    lists.delete(0,END)
    appraisal.delete("1.0",END)

def read_f(file):

    for line in lists_f:
        lists.append(line.rstrip())
    return lists

app = Tk()
app.title(" MP3 Player " )

Label(app,text = "lists:").pack()
lists = StringVar()
lists.set(None)
options = read_f("mp3.txt")
OptionMenu(app,lists,*options).pack()

为什么会出现错误?我该如何解决这个问题?

推荐答案

您需要向 Text.get() 函数传递一个开始和停止索引，指示 Text 你想要的小部件.

You need to pass the Text.get() function a start and stop index indicating what part of the text in the Text widget you want.

如果你想获取Text小部件中的所有文本，你可以使用

If you want to get all the text in the Text widget, you can use

appraisal.get('1.0', END)
