python-redisRedis transactions using multi and exec

Pipelines use transactions by default, so we have to use pipelines for transactions instead of MULTI and EXEC methods:

r = redis.Redis()

p = r.pipeline()
p.set('critical', 'val')
p.execute()ctrl + cgithub

`redis.Redis` connect to Redis server	`r.pipeline()` create Redis pipeline to execute transaction
`p.set` sample `set` command inside transaction (pipeline)	`p.execute()` commits transaction (executes pipeline commands)

import redis

r = redis.Redis()

p = r.pipeline()
p.set('critical', 'val')
p.execute()
