Question

I am using easyzone and dnspython to extract DNS records from a zone file. When extracting A records I am given back a string and an object in a tuple. I am new to Python coming from PHP and am not quite sure how to get at this object to get the value of it? I had no problems getting the string value in the tuple.

In this code snippet I iterate through the A records and write the values into a CSV:

    # Write all A records
    for a in z.names.items():
        c.writerow([domain, 'A', a.__getitem__(0), a])

a contains the following:

('www.121dentalcare.com.', <easyzone.easyzone.Name object at 0x1012dd190>)

How would I access this object within a which is in the 2nd half of this tuple??

You can use indices to get items from a tuple:

sometuple[1]

just as you can do with lists and strings (see sequence types).

The documentation of easyzone is a little on the thin side, but from looking at the source code it appears the easyzone.easyzone.Name objects have .name, .soa and .ttl attributes:

print sometuple[1].name

The .soa attribute is another custom class, with .mname, .rname, .serial, .refresh, .retry, .expire and .minttl properties.
