Best way to enumerate something in python

[Larry Bates]

David,

You may have to give us more detail about what
you want to do, but here goes:

listofcolumns=('field1','field2','field3')
for column in listofcolumns:
    <do something>

Most of the time I find that putting the names
in a dictionary with the column name as key and
offset as the value seems to work better.

dictofcolumns={'field1':1, 'field2': 2, 'field3':3}

value_for_field3=row[dictofcolumns['field3']]

For your second question I think you should
take a look at os.path.getatime, .gmtime, getsize
they are easier to use.
