>>> db['guido'].job

'BDFL'

>>> list(db['guido'].name)

['G', 'v', 'R']

>>> list(db.keys())

['sue', 'bill', 'nobody', 'tomtom', 'tom', 'bob', 'peg', 'guido']

Here in action again is the original database script we wrote in Example 1-19 before
we moved on to GUIs and the web; there are many ways to view Python data:

...\PP4E\Preview> dump_db_classes.py

sue =>

Sue Smith 60000

bill =>

bill 9999

nobody =>

John Doh None

tomtom =>

Tom Tom 40000

tom =>

Tom Doe 90000

bob =>

Bob Smith 30000

peg =>

1 4

guido =>

GvR <shrubbery>

Smith

Doe

Future directions

Naturally, there are plenty of improvements we could make here, too:

• The HTML code of the initial input page in Example 1-33, for instance, is some-
  what redundant with the script in Example 1-34, and it could be automatically
  generated by another script that shares common information.
