Hi, joining late. I think you are talking about modifying a running program's code and data from an external process. My first guess at the closest Python can come is: import shelve configs= shelve.open( 'configs.dat' ) #stuff for some computation: calc= Calc( ) calc.precision= configs[ 'precision' ] calc.compute( ) All well and good if you can synchronize access to 'configs.dat', but a subclass of shelve.DbfilenameShelf could accomplish that. For background, "a shelf is a persistent, dictionary-like object" (docs). 'configs.dat' would reside on disk, so any process could access it. -- http://mail.python.org/mailman/listinfo/python-list
