Another aspect of this has to do with line length. I regularly set my editor window width to around 100 columns. But if you exclude indentation whitespace, my lines are usually much shorter than that. There is a limit to the length of text lines that a human reader can cope with (which is why newspapers, for example, tend to have a many-column layout). Using two-dimensional layout and indentation helps to keep the (non-whitespace) line length within reasonable limits. -- https://mail.python.org/mailman/listinfo/python-list
