Re: [Pyobjc-dev] Obtain data from an Address Book card

[Ronald O. <ron...@ma...>]

The script below creates a CSV file with all records in de AddressBook using the AddresBook framework. (This is the exportBooks.py script from the examples directory in the pyobjc-framework-AddressBook archive).

The Python API to AddressBook is the same as the Objective-C one, in general Objective-C based examples should help to get you going with accessing the same APIs using PyObjC.

You might consider using py-appscript instead:

>>> from appscript import *
>>> my_card = app("Address Book").my_card.properties()
>>> [my_card.get(f) for f in (k.first_name, k.last_name, k.organization)]
[u'Ned', u'Deily', k.missing_value]
