I am creating a text editor on a Mac and am having trouble with file saving. I can open, save as and save files but the save function stops working after I call self.close. I get this error:
Exception in Tkinter callback
Traceback (most recent call last):
File "/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/lib-tk/Tkinter.py", line 1536, in __call__
return self.func(*args)
File "Test1.py", line 43, in save
self.f1=open(self.file, "w+")
TypeError: coercing to Unicode: need string or buffer, file found
How can I get the directory as a string of buffer to fix the error?
Here is my code:

self.fm=Menu(self.m1, tearoff=0)
self.fm.add_command(label="Open", accelerator="Cmd+O", command=self.open)
#these two don't work first time...
self.fm.add_command(label="Save", accelerator="Cmd+S", command=self.save)
self.fm.add_command(label="Save As", command=self.saveas)
self.fm.add_command(label="Close", command=self.close)
self.fm.add_separator()
