Perhaps better is using enumerate:

>>> attributeNames = {}
>>> for n,attribute in enumerate(['foo', 'bar']):
 attributeNames["AttributeName.%d" % (n+1)] = attribute

>>> attributeNames
{'AttributeName.1': 'foo', 'AttributeName.2': 'bar'}

However,  mapping indexes to names should be more useful:

>>> aNames = dict(enumerate(['foo', 'bar']))
>>> aNames
{0: 'foo', 1: 'bar'}
