Redis list is simply a list of strings, sort insertion order. Redis can add elements in the list at the head or tail of the list.
The maximum length of the list is 2 ^ 32 - 1 elements (i.e. 4,294,967,295, each list can store more than four billion elements).
Examples
127.0.0.1:6379 Redis> LPUSH mylist "Redis"
(Integer). 1
Redis 127.0.0.1:6379> LPUSH mylist "MongoDB"
(Integer) 2
Redis 127.0.0.1:6379> LPUSH mylist "MySQL"
(Integer). 3
Redis 127.0 .0.1: 6379> 10 LRANGE mylist 0
. 1) "MySQL"
2) "MongoDB"
. 3) "Redis"

in the above example, the three values of the command list LPUSH Redis inserted entitled "mylist" in.
