The reverse() method of lists reverses the list in-place, and returns
None on purpose. Almost everybody finds this surprising when they
discover it for the first time. Many people (myself included) consider
it a design flaw. But, it is an intentional design decision, not a bug. This thread has been closed and replies have been disabled. Please start a new discussion. Similar topics
