Python DB that supports numbers

[Randall Hopper]

I'm looking for a very simple Python DB which supports:

     1) ints and floats as keys and values, 
     2) performs DB access in the client, and 
     3) stores the DB on disk.  

Just a simple DB for quick projects without the setup headache of
server-based database systems.

For example, on the following table I just want to: "select * where
column_1 is 1".  I'm using raw binary files now, but I'd prefer something
more self-describing like an SQL table.

     1       10       1.814  177.1   13.61   73.2
     1       5        1.624  182.5   -9999   -9999
     1       2        1.259  185.9   13.24   73.9
     2       10       2.672  181.4   13.59   72.5
     2       5        2.423  183.2   -9999   -9999
     2       2        1.902  190.7   13.27   73
     3       10       3.208  181.9   13.46   72.1
     3       5        2.787  186.6   -9999   -9999
     3       2        2.17   194.7   13.16   72.3

Does anything like this exist in Python?

Thanks,

Randall
