The tuple returned by getgrnam contains four fields:
the group id (gr_gid), a list of group members (gr_grmem),
the group name (gr_name), and the group password (gr_passwd).
If you want to see if user 'john' is in the list of group members,
use:
if 'john' in agroup.gr_mem:
print "Found john in group wheel"
If you want to see if a password was set:
if agroup.gr_passwd == "":
print "No group password was set for group wheel"
and so on.
