Hi Fredrik, thank you for saying that I am > ... posting silly assertions. I didn't born " Python expert", and I am hardly trying to learn something. I don't like classes but this assertion (silly... I agree) is due to the fact that "I don't understand them well" (I hope to change mind in a near future). Another item (for me...) difficult, is "import modules", and "plenty of information" (as you said) does not help me much: the mechanism of variable visibility and namespaces is not clear to me. It will be enough an example of the various type of imports and they difference in terms of namespaces or, better, of something you can see on your monitor, or print like, for example, a dictionary. As you can see from my replay to Steve Holden, I have abandoned my project on flowcharting. I must study (as you adviced me)... Bye.
