Delete elements of list with certain length
Clash Royale CLAN TAG#URR8PPP
$begingroup$
I have a list containing some other lists having different lengths. I want to remove some of the lists with a certain length. For example, I have
a = 0, 5, 2, 15, 6, 9, 3, 1, 5, 5, 5, 4, 4, 5, 6, 5;
I want to remove some sub-lists of a having length 1. I mean, I want the result to be as
0, 5, 2, 15, 6, 9, 3, 5, 5, 5, 4, 4, 5, 6
How can I do that using Mathematica?

Select[a, Length@# != 1 &]
0, 5, 2, 15, 6, 9, 3, 5, 5, 5, 4, 4, 5, 6
Also
GeneralUtilities`Discard[a, Length[#] == 1 &]
0, 5, 2, 15, 6, 9, 3, 5, 5, 5, 4, 4, 5, 6
and
DeleteCases[a, _?(Length@# == 1 &)]
0, 5, 2, 15, 6, 9, 3, 5, 5, 5, 4, 4, 5, 6

This might be faster than klgr's solutions on large lists:
Pick[a, Unitize[Length /@ a - 1], 1]
Select and DeleteCases are known to be kind of slow.
