This is a simple notepad program that i am currently writing. Most things are working but cannot get the save to work. Where i have defined save i don't know how to create the save function(not save as).

I am using python 3.4 in windows 8.1. Thanks.
Here's a quick example of a save and save as function, with comments:
def save(self):
contents = self.textbox.get(1.0,"end-1c") #store the contents of the text widget in a str
try: #this try/except block checks to
with open(self.f, 'w') as outputFile: #see if the str containing the output
outputFile.write(contents) #file (self.f) exists, and we can write to it,
except AttributeError: #and if it doesn't,
self.save_as() #call save_as
def save_as(self):
contents = self.textbox.get(1.0,"end-1c")
self.f = tkFileDialog.asksaveasfilename( #this will make the file path a string
defaultextension=".z", #so it's easier to check if it exists
filetypes = (("ztext file", "*.z"), #in the save function
("zytext", "*.zy")))
with open(self.f, 'w') as outputFile:
outputFile.write(contents)
There are other ways to do this, but this will work in a pinch. Just think about what the save
function needs: text to save and a file to save in, and go from there.
