Please help me this must be really simple - I want to add items to a list and set items in a list. I thought append and setItem would solve all my problems. I tried this simple filter:

x = list(1,2,3)
setItem(x, 2, 6)
x.append(10)

y = x[2]
z = x[3]
emit y, z

I expected to get output y = 6 and z = 10 but I get index out of bounds when I try to call x[3] and x[2] never seems to get set to the new value.

Any help pointing me in the right direction would be much appreciated.

Hi Dave,

Both the setItem and append functions will return a copy of the list with the updated values; however, you need to set that to "something" in order to preserve the changes. See below as an example to get the results you expected:

x = list(1,2,3)
x = setItem(x, 2, 6)
x = x.append(10)

y = x[2]
z = x[3]
emit y, z
