如何在python制成的记事本上打开文本文件?

标签: python tk notepad

我正在尝试添加一个允许我在python内置记事本中打开文本文件的功能,但是此错误显示TypeError:预期的str,字节或os.PathLike对象,而不是列表

我实际上真的是编程新手,我正在按照本教程讲解如何在python上制作记事本,我曾尝试导入os,但我不知道如何使用它。预先感谢

from tkinter import Tk, scrolledtext, Menu, filedialog, END, messagebox

#Root main window
root = Tk(className=" Text Editor")
textarea = ScrolledText(root, width=80, height=100)
textarea.pack()

# Menu options
menu = Menu(root)
root.config(menu=menu)
filename = Menu(menu)
edicion = Menu(menu)


# Funciones File

1 个答案:

答案 0 :(得分:0)

该错误提示您正在发生的事情。

您遇到此错误:TypeError: expected str, bytes or os.PathLike object, not list

这表明这一行:

file = open(file,"r+")

正在尝试打开列表。为什么会这样呢?好吧,您在此处用于分配file变量的函数是 返回文件列表 ,而不是单个文件名:

file = filedialog.askopenfiles(parent=root, mode='r+', title="Select a file")

您是否有可能误读了本教程,您应该写的是:

file = filedialog.askopenfilename(parent=root, mode='r+', title="Select a file")
