huh... ok, the thing is that there will actually be no code in the
config file, just some variables and values.. it will be more like a
"setting file"... so no execution of the config file is necessary, just
getting and setting variables...

thank you for the tip!

yes I will use it

Yes i do :) i just did not c/p code from my script but from some webpage
:)) i have print (config["value1"])

thank you i am using configparser... the only problem as i mention in
another post is that it reads lists as string... so some additional
parsing is necessary..
