Tkinter使用asksaveasfile保存文本文件

Question

我试图将大量变量保存到文本文档中，但当我单击“保存”按钮时出现错误，当我使用asksaveasfile或asksaveasfilename时。

代码的相关部分（它都会约一百名不同的变量，但为了节省空间，我不会写所有的人）是：

from tkinter import * 
from tkinter.filedialog import * 
def save_doc(): 
    text_file=open(asksaveasfile, mode ='w') 
    text_file.write(nombrePatrocinado+"\n") 
    text_file.write(apellidoPaternoPatrocinado+"\n") 
    text_file.close() 
saveDocBTN=Button(text="Save", command=save_doc) 
saveDocBTN.grid(row=0,column=6) 

当我使用它，它说

Exception in Tkinter callback 
Traceback (most recent call last): 
    File "/usr/lib/python3.4/tkinter/__init__.py", line 1536, in __call__ 
    return self.func(*args) 
    File "/home/juanelo/Downloads/launcher.py", line 662, in save_doc 
    text_file=open(asksaveasfile, mode ='w') 

TypeError: invalid file: <function asksaveasfile at 0xb5e973d4> 

另外一个我想是非常相同：

from tkinter import * 
from tkinter.filedialog import * 
def save_doc(): 
    text_file=open(asksaveasfilename) 
    text_file.write(nombrePatrocinado+"\n") 
    text_file.write(apellidoPaternoPatrocinado+"\n") 
    text_file.close() 
saveDocBTN=Button(text="Save", command=save_doc) 
saveDocBTN.grid(row=0,column=6) 

当我尝试，我得到

Exception in Tkinter callback 
Traceback (most recent call last): 
    File "/usr/lib/python3.4/tkinter/__init__.py", line 1536, in __call__ 
    return self.func(*args) 
    File "/home/juanelo/Downloads/launcher.py", line 662, in save_doc 
    text_file=open(asksaveasfilename) 
TypeError: invalid file: <function asksaveasfilename at 0xb5df82b4>

您未拨打asksaveasfilename();你只是参考它。您需要添加括号：

text_file=open(asksaveasfilename())
