There are several options but I'd recommend writing a 
method of the Saving class to fetch the filename.
You also need to create a member attriobute of Saving 
to store the value of course...

     def apply(self):   #as above except last line
         dir = self.e1.get()
         fn = self.e2.get()
         self.name = dir + fn  # assign to instance variable

     def getName(self):   # inside Saving class
        return self.name  # return instance variable

Then when you create the Saving class you assign to 
a local variable.

     def doSave(self):		# inside Pyshell class
         saveDialog = Saving(f) # auto calls apply etc
         filename = saveDialog.getName()
         self.saveText(filename)
         del(saveDialog)

         
> how to pass the variable sav from Saving to PyShell. 

Don't pass the data - it belongs to the object. Get the 
object to give you the data on request. Thus when you 
create the instance of Saving you keep the reference 
and use it to ask for the filename.
