It’s because your list is in a list. You have a list of a single item (list). That single item reversed is still that single item. There’s no need for brackets in your codeblock.

The syntax for reversing a list in python is myList.reverse().

[Hamish]

@L2 on the list reverse node, or remove the [] from your code block.

You’ve made a list of lists (the … already forms a list, the [] isn’t required unless you want make sublists or change the level) so the list.reverse node is reversing your list of 1 items at L3 instead of your list of 26 items at L2

If you’re in Python, this a bit of a trick you can use with list slice syntax as well:

@Draxl_Andreas

X = (IN[0]).reverse

OUT = X

for info, the reverse method is an “in-place” method
