Thanks Bob, the 'exec' saved me. But I'm not sure how I could solve my 
specific problem with a dict, since my 'var' variable is a string I'm 
getting from a database-field, that refers to the name of another field, 
which should be changed. So I see no other way than resolving the string 
in some instance - or is there?
