until the New programmer (I hate the word noob, it looks too derogatory even when that is not the intention) has learnt enough to be using a logging module i can see no alternative to using print for debugging purposes. I would agree that in production code they are often the wrong option (although still valid for CLI applications.) -- You can't get there from here. -- https://mail.python.org/mailman/listinfo/python-list
