slicing a bsddb table, eg. for rec in bsddb["AArdvark":"zebra"]:print rec

P: n/a
#!/bin/env python
import bsddb

test=bsddb.btopen("test.tbl")
for m in "JFMATQPHSOND":
test[m]="Profit for month "+m+" $1B"

def subyear_report(record_selection):
for data in record_selection.iteritems(): print data

# I was expecting a slice of an index file to yield a
# generator so not all the records need to be read from disk....
subyear_report(test["Apr":"Sep"])

"""
I have tried a few ideas.... but is there a simple way to convert this
["Apr":"Sep"] slice of a file into a generator of the requested records?

(I tried UserDict and got a bit further...)

Any hints?

ThanX
