Using a text file to set label expression in ArcPy

I am currently using the lyr.labelClasses[0].expression property to label features in ArcMap from a Python script.  I am wondering if it is possible to set this expression property from a string stored in a text document.  If so, what would be the best way of going about this?  Any help is greatly appreciated.  Thanks in advance.
