loop through SDE connections

What want a python loop to go through a list of different SDE connections. I have this:

SDEConnect = 'Database Connections\\Atlas2013' EditorList[x] 'as' EditorList[x]'.sde\\sde.CHELAN.LandBase\\sde.CHELAN.Property_Polygons'

That has an output of: ('Database Connections\\Atlas2013', 'cathye', 'as', 'cathye', '.sde\\sde.CHELAN.LandBase\\sde.CHELAN.Property_Polygons')

which doesn't work in the script. How do I format the code to correctly insert the value from the EditorList?

Thanks
Jeff
