Sample

Getting Started

$ python
>>> import redis
>>> r = redis.Redis(host='192.168.11.11', port=6379, db=0)
>>> r.set('foo', 'bar')
True
>>> r.get('foo')
'bar'
>>>
>>> r['name'] = 'patrick'
>>> r['name']
'patrick'
>>>

Note

To connect to a Redis server on localhost:
```
r = redis.Redis()
```
See Configuration to set-up Redis to allow remote connections.

Status

Continuing from the previous sample, we can get status information from the Redis server:

>>> r.info()
{'total_connections_received': 2, 'db0': {'keys': 3, 'expires': 0}, 'connected_clients': 1, 'used_memory': 619878, 'last_save_time': 1294952249, 'bgrewriteaof_in_progress': 0, 'changes_since_last_save': 3, 'role': 'master', 'uptime_in_seconds': 195, 'uptime_in_days': 0, 'bgsave_in_progress': 0, 'connected_slaves': 0, 'multiplexing_api': 'epoll', 'arch_bits': 64, 'total_commands_processed': 10, 'redis_version': '1.2.0'}

Keys

Continuing from the previous sample, we can manipulate keys in other ways:

::

>>> r.keys('*')
[]
>>> r.set('key-1', 'Value 1')
'OK'
>>> r.keys('*')
[u'key-1']
>>> r.get('key-1')
u'Value 1'

Capped Log
