my mistake is because I have no problem to do that using Prolog which use an
interpreter as Python. I thought that the variables in the main global memory
space (associated with the command line environment) were kept, although the
code that use it could change.
As you explain me, Python behave like a compiled language: any time I make a
change in the code, I have to "compile" it again, and re-run (and re-load the
data). There is nothing to do.
Thank you!
