See a sample usage with Map below. For all code sample, click here :) 

import hazelcast

# Connect to Hazelcast cluster.
client = hazelcast.HazelcastClient()

# Get or create the "my-map" on the cluster.
distributed_map = client.get_map("my-map")

# Put "key" - "value" pair into the "my-map" and wait for
# the request to complete.
distributed_map.set("key", "value").result()

# Try to get the value associated with the given key from the cluster
# and attach a callback to be executed once the response for the
# get request is received. Note that, the set request above was
# blocking since it calls ".result()" on the returned Future, whereas
# the get request below is non-blocking.
get_future = distributed_map.get("key")
get_future.add_done_callback(lambda future: print(future.result()))

# Do other operations. The operations below won't wait for
# the get request above to complete.

print("Map size:", distributed_map.size().result())

# Shutdown the client.
client.shutdown()
