IDLE sometimes slows things down and can occasionally lock
up with Tkinter (probably because it is itself written in Tkinter!).
It's usually better and faster to run Tkinter programs from a separate
console window.
class SeatButton(tk.Button):
def clicked(self):
self.occupied = not self.occupied
if self.occupied:
self["bg"] = OCCUPIED
###################################
text_file=open(self.filename,"w")
text_file.write(self.filename)
text_file.close
###################################
else:
self["bg"] = FREE
################################
os.remove(self.filename)
#################################
OK, I see.

What you are doing is fine, I'd leave the button click bit as it is if you
really want to
create/delete files. As I said originally this is an unusual thing to do but
you
may
have more going on behind the scenes or planned.
But normally I would just keep all the data about whether the seats were booked
or
not in memory and then save it all in one go into a single file at the end of
the program.
Or, for a long running program, I might store it in a file but I'd use a single
file - probably
a shelve file. (If you are not familiar with shelves they are special files
that
act like
dictionaries in your code.)
