I am really battling to get dnspython to read a zone file, I always get stuck with SOA and I have tried combinations of different zones files and python scripts.
Zone file(From http://agiletesting.blogspot.com/2005/08/managing-dns-zone-files-with-dnspython.html):
$TTL 36000
example.com. IN SOA ns1.example.com. hostmaster.example.com. (
2005081201 ; serial
28800 ; refresh (8 hours)
1800 ; retry (30 mins)
2592000 ; expire (30 days)
86400 ) ; minimum (1 day)
example.com. 86400 NS ns1.example.com.
example.com. 86400 NS ns2.example.com.
example.com. 86400 MX 10 mail.example.com.
example.com. 86400 MX 20 mail2.example.com.
example.com. 86400 A 192.168.10.10
ns1.example.com. 86400 A 192.168.1.10
ns2.example.com. 86400 A 192.168.1.20
mail.example.com. 86400 A 192.168.2.10
mail2.example.com. 86400 A 192.168.2.20
www2.example.com. 86400 A 192.168.10.20
www.example.com. 86400 CNAME example.com.
ftp.example.com. 86400 CNAME example.com.

As for the Zone file I have downloaded a zone file from Godaddy.com, the same issue. I have taken a zone file from a PRODUCTION Bind server(Secondary Zone), same error.
So I am really stumped, any assistance will greatly be appropriated.
