Arguments
str
required
The array key.
Response
The number of slots containing values, or zero for a missing key.
redis.arset("readings", 1000, "sample")
print(redis.arcount("readings")) # 1
print(redis.arlen("readings")) # 1001
ARCOUNT
Count the occupied slots in an array.
redis.arset("readings", 1000, "sample")
print(redis.arcount("readings")) # 1
print(redis.arlen("readings")) # 1001
For sparse arrays, this differs from ARLEN, which returns the highest occupied index plus one.
See the server command reference for protocol details.
