[SOLVED] How do I programmatically get a list of packages from apt?

Issue

How can I use Python/python-apt to programmatically get the same result as "dpkg --get-selections"?

Solution

To display the first five packages:

import apt_pkg

apt_pkg.init()
cache = apt_pkg.Cache()

i = 5
for pkg in cache.Packages:
  print(pkg)
  i -= 1
  if i < 0:
    break

The output (when run on my Ubuntu system):

$ python apt_package_list.py
Reading package lists... Done
