bplustree lib

[Pigio®]

There is someone that has used "bplustree"  llib?

THIS IS MY PROBLEM:

>>> file=open('test','w+b')
>>> from bplustree import *
>>> B = SBplusTree(file, 0, 200, 20)
>>> B["this"] = 'pippo'
Traceback (most recent call last):
  File "<stdin>", line 1, in ?
  File "bplustree.py", line 1592, in __setitem__
    self.tree[key] = seek
  File "bplustree.py", line 1064, in __setitem__
    if type(value)!=IntType: raise ValueError, "value must be int"

WHAT'S HAPPEN?

thers is another b+tree python implementation?

Thanks
