Python node adds a level to an input list

[daniel.peel]

If i feed a list into a Python node it gains an additional level (list in list) which means that various subsequent operations i want to perform don’t work unless i extract the particular level i need. Its not a big problem but im curious to know why it does this and if there is a way of keeping the input list at a single level?

It should be IN[0]

I am not very sure why this happens,may be because it treats your variable as a list but to avoid it you can use list.append
