[Jython-users] jython shelve problem

[J. V. B. <jev...@tu...>]

I'm trying to use shelve in a small Jython program, but every time I 
try to run it, I get an error message:

"TypeError: open() got an unexpected keyword argument 'writeback'"

Here's my code:

#---- begin -------#

#! c:\jython2.2.1\jython.jar

import os, sys, shelve
shelfpath = sys.path[0]
print
print "Path to the shelf directory:", shelfpath
print
path = ('%s''\\''%s''.''db') % (shelfpath, 'accounts_database')
print
print "This is the path to the shelf:" , path

file = shelve.open(path, 'c', writeback=True)
print file

#---- end --------#


My configuration:
Windows Vista
Eclipse 3.3.2
Jython2.2.1
Python2.5.2
jdk1.5.0_12

Jython, Python and Java JRE all set up to run in Eclipse. I'm trying to 
run this program in Eclipse.

Why doesn't the "writeback" argument work?


Thanks in advance for any help
