用Tkinter写了个记事本小程序，有点问题不知道怎么解决。。。
代码如下from tkinter import *

在保存和另存为文件的时候会弹个错误，从来没见过，希望有大佬帮忙处理一下！！
TypeError: expected str, bytes or os.PathLike object, not _io.TextIOWrapper
tkinter.filedialog.asksaveasfilename():选择以什么文件名保存，返回文件名
tkinter.filedialog.asksaveasfile():选择以什么文件保存，创建文件并返回文件流对象
干嘛要返回文件流对象？改一下
然后建议保存时直接添加后缀.txt
def save_as(self,event=None):
input_file = filedialog.asksaveasfilename(filetypes=[("所有文件", "*.*"), ("文本文档", "*.txt")])
print(input_file)
if input_file:
self.file_name = input_file+'.txt'
self.write_to_file(self.file_name) 疾风怪盗 发表于 2020-10-9 10:40
tkinter.filedialog.asksaveasfilename():选择以什么文件名保存，返回文件名
tkinter.filedialog.asksavea ...
原来是这样啊，懂了懂了，谢谢大佬
