Python iterating through object attributes [duplicate]

UPDATED

For python 3, you should use items() instead of iteritems()

PYTHON 2

for attr, value in k.__dict__.iteritems():
        print attr, value

PYTHON 3

for attr, value in k.__dict__.items():
        print(attr, value)

This will print

'names', [a list with names]
'tweet', [a list with tweet]
