import tkinter as tk

list = []

def add():
    element = entry.get()
    entry.delete(0,1000)
    list.append(element)

def save():
    with open("save.txt","w") as f:
        for element in list:
            f.write(element + ",")

root = tk.Tk()

frameList = tk.Frame(root)
frameList.pack()

entry = tk.Entry(root)
entry.pack()

btnAdd = tk.Button(root,text="add",command=add)
btnAdd.pack(pady=5)

btnSave = tk.Button(root,text="save",command=save)
btnSave.pack()

root.mainloop()

此代码在保存时给我这个错误：

Exception in Tkinter callback
Traceback (most recent call last):
  File "C:\Users\HP\AppData\Local\Programs\Python\Python37\lib\tkinter\__init__.py",line 1705,in __call__
    return self.func(*args)
  File "C:/Users/HP/Desktop/python/github/write.py",line 11,in save
    with open("save.txt","w") as f:
FileNotFoundError: [Errno 2] No such file or directory: 'save.txt'

如果我创建文件“ save.txt”，则会显示：

During handling of the above exception,another exception occurred:

Traceback (most recent call last):
  File "C:\Users\HP\AppData\Local\Programs\Python\Python37\lib\tkinter\__init__.py",line 13,in save
    f.write(element + ",")
OSError: [Errno 9] Bad file descriptor

请，您能帮我解决这个问题吗？

对不起，最后一句话，但是我必须添加一些“非代码”来发布问题，所以从现在开始，我会说一些随机的东西，对不起
