I think you’re bumping into semantics which are similar to the distinction between list.append() and list.extend(). I know that this works for me: myredis.lpush(‘foo’, *[1,2,3,4]) … note the * (map-over) operator prefixing the list!
Redis is an in-memory but persistent on disk database, so it represents a different trade off where very high write and read speed is achieved with the limitation of data sets that can’t be larger than memory. Another advantage of in memory databases is that the memory representation of complex data structures is much simpler … Read more
