Quickstart¶
>>> from ssdb import SSDB
>>> import time
>>> ssdb = SSDB(host='127.0.0.1', port=8888)
>>> ssdb.multi_set(set_a='a', set_b='b', set_c='c', set_d='d')
4
>>> ssdb.multi_set(set_x1='x1', set_x2='x2', set_x3='x3', set_x4='x4')
4
>>> ssdb.multi_set(set_abc='abc', set_count=10)
2
>>> ssdb.multi_hset('hash_1', a='A', b='B', c='C', d='D', e='E', f='F',
... g='G')
7
>>> ssdb.multi_hset('hash_2',
... key1=42,
... key2=3.1415926,
... key3=-1.41421,
... key4=256,
... key5='e',
... key6='log'

>>> ssdb.get('set_a')
'a'

>>> ssdb.scan('set_x ', '', 10)
{'set_x1': 'x1', 'set_x2': 'x2', 'set_x3': 'x3', 'set_x4': 'x4'}
>>> ssdb.delete('set_abc')
True
>>> ssdb.hget("hash_1", 'a')
'A'
>>> ssdb.hexists('hash_2', 'key2')

>>> ssdb.hlist('hash_ ', 'hash_z', 10)
['hash_1', 'hash_2']
>>> ssdb.hscan('hash_1', 'a', 'g', 10)
{'b': 'B', 'c': 'C', 'd': 'D', 'e': 'E', 'f': 'F', 'g': 'G'}
>>> ssdb.zget("zset_1", 'b')
20
>>> ssdb.zset("zset_1", 'z', 1024)
True
>>> ssdb.zset_exists('zset_2')
True
>>> ssdb.multi_zget('zset_1', 'a', 'b', 'c', 'd')
{'a': 30, 'c': 100, 'b': 20, 'd': 1}
>>> ssdb.zkeys('zset_1', '', 0, 200, 3)
['g', 'd', 'b']
>>> ssdb.zscan('zset_1', '', 0, 200, 10)
