Python List Reverse Function

Question

Python Novice. Need to create a list which is a reverse of the previous list. Ran the follow code:

list_10 = [1,10,20,4,40,14]
list_11 = list_10.reverse()
print (list_11)

I get an output that says "None"

Any suggestions?

`reverse()` reverses in place. It doesn't return anything. Use `list_11 = list(reversed(list_10))` — Mark, Apr 16 '20 at 00:11
You can also use slice `list_11 = list_10[-1::-1]` to make a copy of the original list in reverse order. — DaveStSomeWhere, Apr 16 '20 at 00:21

Because reverse() reverses the list in place, it returns none.

Try this.

list_10 = [1,10,20,4,40,14]
list_10.reverse()
list_11 = list_10

the op likely wants to create *a new list* – juanpa.arrivillaga Apr 16 '20 at 00:16
