How to apply `Length` in all elements
Clash Royale CLAN TAG#URR8PPP
$begingroup$
I want to apply Length in each element from a list.
For example:
My list is: 1,2,3,4,5,6
How to apply Length in each element of this list?
Length[1]
Length[2,3]
Length[4,5,6]
I have tried to use Thread, but doesn't works:
In[235]:= Thread[Length[1, 2, 3, 4, 5, 6]]
Out[235]= 3
The result that I want is some like:
1
2
3
Which is the number of elements in each element.

If[AtomQ @ #, 1, Length @ #] & /@ 1, 2, 3, 4, 5, 6
1, 2, 3
If the input list does not contain (thanks: @corey979), you can also use:
Length /@ 1, 2, 3, 4, 5, 6 /. 0 -> 1
(* or Map[Length]@1, 2, 3, 4, 5, 6 /. 0 -> 1 *)
1, 2, 3

A mildly adjusted version of the nice Charting answer by yode is to apply a list to each element and flatten:
Length@Flatten@List@#&/@1, 2, 3, 4, 5, 6
