Hello again, I am continuing responding to the questions that Brett, the fantastic reader of my books, sent a few weeks ago. I am pleased to confirm that he has found the response to his first question on Python and Object orientation really useful. He even provided me with some clarifications that show that he has more than understood the answer. You can see that first response here.
This time though it is all about virtual environments, starting with the difference between them and containers. See the response here.
