How can I use `--lines` `--row` modifiers in `ps` command

I often used the following command,
ps -eo pid,cmd,pcpu,pmem --sort=-pcpu | head
But in the man page I saw the following to output modifiers,
--lines n
Set screen height.
--rows n
Set screen height.
As if these modifiers can limit row height then I don't have to use any kind of piping which gives me a bit comfort on writing scripts with python subprocess.
But I have no idea how can I use them. As I have already tried adding them at the end of the command.

The screen height doesn’t limit the total output, it determines how often the header is repeated (if requested):
ps -eo pid,cmd,pcpu,pmem --sort=-pcpu --lines=20 --header
will repeat the header every twenty lines (so you’ll get a header, nineteen lines of output, a header, etc.).
