Yes -- li.reverse() returns None. "print None" prints nothing. > val = 'string' > li = list(val) > li.reverse() > print li > > returns what I want. I'm afraid not. li.reverse() still returns None, but this time you print li, and this shows the reversed list. As already explained, li.reverse() modifies the existing list. What to use here depends on what you want to achieve: If you really want to reverse the list (i. e. re-sort the list in memory, and perhaps work with it afterwards), use "li.reverse()". If you just want to have all its members in reverse order, use the builtin reversed(li) (which is an iterator giving you li's members from back to front when iterating over it).
