Return or exclude the nth lines supplied from stdin as output on stdout. See the Rust version of this utility here: nth_rs.
pip3 install nth_py$ dmesg | nth 0 1 2 3

To better illustrate, let's enumerate each line of stdin:
$ dmesg | count | nth 0 1 2 3
0 [ 4.095065] xhci-hcd xhci-hcd.3.auto: xHCI Host Controller
1 [ 4.100328] xhci-hcd xhci-hcd.3.auto: new USB bus registered, assigned bus number 4
2 [ 4.107985] xhci-hcd xhci-hcd.3.auto: Host supports USB 3.0 SuperSpeed
3 [ 4.109677] mmc_host mmc0: Bus speed (slot 0) = 50000000Hz (slot req 52000000Hz, actual 50000000HZ div = 0)See LICENSE. If you'd like to use this project with a different license, please get in touch.
