OK, I didn’t notice you were specifically checking for packages with
status = installed. Here’s an update to my code that includes such a
check:

    import subprocess

    kernel_list = list \
      (
        n
        for s, n in
        (l.split("\t", 1)
            for l in
            subprocess.check_output
              (
                args = ("dpkg-query", "-f" "${Status;-1}\t${Package}\n", "-W", "*linux-image*"),
                text = True
              ).split("\n")
            if l != ""
        )
        if s == "i"
      )

    print(kernel_list)

The output list is much shorter. ;)
