you can’t, but you can pass a table as arguments
and do #table and you get the amount of values

You can use select:

function CreateParts(...)
	print(select('#',...)) -- 3
end

CreateParts(4,3,2)

The variadic argument takes all of the passed arguments and gives them that name. In order to see what is the length of it, try doing the following:

function CreateParts(...)
     local args = {...}
     print(unpack(args)) -- what is in the table (will print "hi" and "ok" for ex)
     print(#args) -- will give you the length.
end

CreateParts("hi", "ok")

It is possible, you just need to loop through the table you get and create the parts.

function CreateParts(...)
    local args = {...}
    for i,v in pairs (args) do
         local part = Instance.new("Part")
         Part.Parent = workspace
    end
end

select is documented, you can pass a number to get arguments after a certain index or pass '#' to get the total number of arguments.
