I want to the value that list number is larger than a+b
but when I using the ‘>=’, it is only return ‘true/false’.
I want to extract number value which is larger than a+b
how can I do…?
Hi @hojukys and welcome, use the node List.FilterByBoolMask

As mentioned before, the ‘node’ based way to do this would be to leverage the List.FilterByBoolMask node.
Alternatively you could use a line of DesignScript in a code block for the whole thing. Something along the lines of this:
DSCore.List.Clean(numberList>a+b ? numberList : null) , false);
Breaking down the statement above, we all the DSCore library, get the List module, and call for the Clean function. Then we use an if statement in the format test ? ValueIfTrue : ValueIfFalse where the test is checking the values in the number list agains the sum of a and b, and the true value is the number from the list, and the false value is a null. By using the false override on the List.Clean function the nulls at stripped out of the list.

thank you!!!
hello, writing DSCore is not mandatory?
but you write like that (you show pedagogy)
to retain Library.Module.Function()
that’s it ?
thank you

OUT = []
for i in IN[0]:
if i >= IN[1]:
OUT.append(0)
else:
OUT.append(1)
Hi,
or via python

In this case I call out the DSCore because the List namespace has a few common collisions with other widely distributed packages. By directly referencing the library we keep error messages from popping up or causing the code to fail for some users.
