Stopping edit session at start of ArcPy script?

Question

I have a simple script that I use to select features from a ArcSDE database and export them to a personal.gdb.

Currently, I have to manually save and stop my edit session in the MXD so that the script can get a schema lock.

I have been trying to use arcpy.da.Editor at the start of the script to automatically end the edit session, but I have not been able to achieve that thus far.

Is this the correct way to end an edit session in the MXD I am running the script in? I would also like to be able to restart my edit session after the script runs.

import arcpy
import os
from arcpy import env
env.overwriteOutput = True
edit = arcpy.da.Editor
edit.startEditing(False, True)
print 'Stopping Edit'
# Delete Feature class from file Geodatabase
arcpy.Delete_management('C:\GIS\BlairMailer\Mailer.mdb\AddressPoint')
print 'Feature Class Deleted'
# Select by attribute
arcpy.SelectLayerByAttribute_management ( "AddressPoint", "NEW_SELECTION", " [DISTRICT] = 'Y'" or "[DISTRICT] = 'y'")
# Export selected feature to Geodatabase
arcpy.FeatureClassToGeodatabase_conversion("AddressPoint",'C:\GIS\BlairMailer\Mailer.mdb')
print 'feature Class Exported'
# Open Mailer
os.startfile(r'C:\GIS\BlairMailer\Mailer.docx')

This is the returned error when I try to run the script with an active edit session.

Runtime error 
Traceback (most recent call last):
File "<string>", line 7, in <module>
TypeError: descriptor 'startEditing' requires a 'Workspace Editor' object but received a 'bool'

As commented by @GISGe, the

arcpy.da.Editor [class] takes a workspace as argument: arcpy.da.Editor(workspace)

whereas you have:

edit = arcpy.da.Editor

See the Syntax section of the Editor class Help
