# Blank lines are punctuation One blank line separates thoughts inside a function; two separate definitions at module level. - A function with no blank lines at all is one paragraph, which is fine when it is short and wrong when it is not. - Do not open a function body with a blank line, and do not close it with one. - Group the statements that belong to one step, then leave a line before the next step begins. Where the blank lines fall is usually where the comments would have gone, which is a good sign that the steps are real.
