------------------
pip install [--user] leveldb
**NB** If you have issues with this step, please contact Russell (power@cs.nyu.edu).
I'm responsible for the PyPi package upload and any resulting errors.
Example Usage
-------------
>>> import leveldb
>>> db = leveldb.LevelDB('./db')
>>> db.Put('hello', 'world')
>>> print db.Get('hello')
world
>>> db.Delete('hello')
>>> db.Get('hello')
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
KeyError
>>> for i in xrange(10):
... db.Put(str(i), 'string_%s' % i)
...
>>> print list(db.RangeIter(key_from = '2', key_to = '5'))
[('2', 'string_2'), ('3', 'string_3'), ('4', 'string_4'), ('5', 'string_5')]
>>> batch = leveldb.WriteBatch()
>>> for i in xrange(1000):
... db.Put(str(i), 'string_%s' % i)
