Either use the output of apt-config or the python-apt equivalents,
depending on which apt-offline backend you are using.

# apt-config version for the apt backend
import subprocess
command = """
# Unset variables in case they are set already
unset trusted
unset trustedparts
# Get the variables from apt
eval $(apt-config shell trusted Dir::Etc::trusted/f)
eval $(apt-config shell trustedparts Dir::Etc::trustedparts/d)
# Securely pass the variables back to python-apt
printf "%s\\0%s" "$trusted" "$trustedparts"
"""
process = subprocess.Popen(['sh'], stdin=subprocess.PIPE,
stdout=subprocess.PIPE)
output = process.communicate(input=command)[0]
trusted, trustedparts = output.split('\x00')

# python-apt version for the python-apt backend
import apt_pkg
apt_pkg.init()
trusted = apt_pkg.config.find_file('Dir::Etc::trusted')
trustedparts = apt_pkg.config.find_dir('Dir::Etc::trustedparts')
