Deleting keys from shelve

Why does a shelve file never get smaller?

I noticed that the shelve file (db.txt, see below) does not change
(get smaller) when deleting a key. The key is deleted but the file
size does not change. I expected the db.txt file to get smaller.

def delete():
s = shelve.open('db .txt')
del s['test3']

I am using Python 2.2.1 on MS Windows. Thanks so much for your help.

When I try to run it under Python for...

Python's docs say that Shelve uses Pickle to serialize its data. However, I've noticed that Pickle can maintain internal links, while Shelve cannot. For instance: >>> d = shelve.open('shelvedata.txt',writeback=True) >>> d= >>> d=d >>> print d {'a': , 'b': } >>> d=2 >>> print d {'a': , 'b': }

Shelve uses dbm and pickle to make a persistent object store. The "db" in "dbm" stands for "database" and while I didn't expect full ACID capability, I'd have thought there'd be at least some minimum gesture towards durability of updates. But say that s is a shelve object. If I say s = value there is no way apparent from the shelve...

Hi! I want to use shelve to store lists which are indexed by an integer key. The keys are not concurrent or anything, they are just defined as integer values. However, shelve complains that I cannot have integer keys. Here's the error: >>> d Traceback (most recent call last): File "<input>", line 1, in ? File "E:\Python23\lib\shelve.py",...
