Append[] is not working for empty list

Question

I am trying to create an empty list and add an element but the list is not being populated.

My code

configsPermTerms = List[]; Append[configsPermTerms, {{0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0,     0, 0}, 8}] Length[configsPermTerms] configsPermTerms

Output

{{{0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0}, 8}}
0
{}

What am I doing wrong?

Are you looking for AppendTo? – bill s Apr 08 '16 at 20:26 — bill s, Apr 08 '16 at 20:26

Look up the difference between

Append

and

AppendTo

Append doesn't reassign the value of the List, while AppendTo does.
