I'm trying to ovveride attribute setting, but I haven't still found
the right way to use all the fancy __get__, __set__ and
__getattribute__ :-)

If the functions are
f1, f2, f3 you could go this way:
def SimulationRun():
if simulation_level = 1: SimulationFunction = f1
else if simulation_level = 2: SimulationFunction = f2
else
and in the rest of the code you can refer to SimulationFunction
instead of explicitly calling
Within gnuplot you can shorten "with" to "w", don't know if it can
work inside a call to Gnuplot.Data()

You need to append the joined string to your new list.
For instance
my_list = ["a", "b", "c"]

It depends on the requirements of the OP.
A possible solution could be:
my_second_list = []
try:
my_second_list.append("".join(my_list))

It's better to use the new-style (always derive from object).
