You can ask the dpkg commands for exactly the info you need, to save
parsing out unwanted cruft. Here’s what I came up with in Python:
import subprocess
kernel_list = subprocess.check_output \
(
args = ("dpkg-query", "-f" "${Package}\n", "-W", "*linux-image*"),
text = True
).split("\n")[:-1]
print(kernel_list)
Here’s (partial) output on my Debian Unstable system:
['linux-image-6.1.0-8-amd64', 'linux-image-6.1.0-8-amd64-unsigned',
'linux-image-6.1.0-9-amd64', 'linux-image-6.1.0-9-amd64-unsigned',
'linux-image-6.10.11-amd64', 'linux-image-6.10.11-amd64-unsigned' ...
'linux-image-6.9.10-amd64', 'linux-image-6.9.10-amd64-unsigned',
'linux-image-amd64', 'linux-image-generic']
