Linking Dictionary Values

[Maan M. Hamze]

Is it possible to link Dictionary values of each key into a text file?  So
the value of a key is a text file somewhere on the PC.  And if so, how do I
instruct Python to open the text file and print into screen when the key of
the text file is used?
Also, is it possible to link a value of a Dictionary key into a Python
function/procedure?  So, if the key is encountered, a way for the
functionprocedure to be run.
