Split List In Two

MIT App Inventor Help
1

Hello,

Looking for some help.
I have a textbox that contains this text.

Input_Text = "Alpha|1,2,3,4,5"

I want to split the text in two lists to read the following.

List_1 = "Alpha"
List_2 = "1,2,3,4,5"

List_1 will be the first value before the "|" symbol.
List_2 will be the remaining values after the "|". Separated by ",".

blocks (1)

Thank you

and if you need second list to be another list

then you need to split it further using ','

If my list looks like this: 1, e, 4, f, 3, g, 5, h, 4, 2.7, y, 0, 3, 1, d (or any other sequence) how do I split it at the fifth element?

I tried using the 'all but first element' block five times in a row, but it feels inefficient. Is there a better way? That is because I only wanted the rest of the list.

There is a list block available for this:

(there is a hack in there to get the last item of the list...shouldn't work but seems to :wink: )

I tried that one, but not that inexistant index2 :wink:
Never thougrh about a possible out of range index2
