I believe the argument to Field.Virtual and Field.Lazy just needs to be a
callable object that takes a Row object as an argument, so you could write
a function and then pass that function.
def myfield(row):
[code to generate field value from row object]
return value
db.mytable.myvirtualfield = Field.Lazy(myfield)
