It all depends on what you will use it for. As said, exec should work,
but it usually is not the way to go - if there's outside input
involved, it's _extremely_ unsafe, if everything comes from inside
your program it's an ugly sledgehammer to crack a nut. So please take
one step back - WHY do you want to do this? Where does this string
"self.abc = 22" come from? What are the values it can have? Can you
create a toy example that shows the problem you want to solve?
