Online examples

redis　127.0.0.1:6379> LPUSH w3codeboxkey redis
(integer)　1
redis　127.0.0.1:6379> LPUSH w3codeboxkey mongodb
(integer)　2
redis　127.0.0.1:6379> LPUSH w3codeboxkey mysql
(integer)　3
redis　127.0.0.1:6379> LRANGE w3codeboxkey 0　10
1) "mysql"
2) "mongodb"
3) "redis"

In the above examples, we used LPUSH Insert three values into the list named w3codeboxkey in the list.
