client = clients.get_wrapped_client(
    endpoints=["http://localhost:2379/"],
    namespace='ns1',
    timeout=100,
)

# KV locks
lock = client.kvlock.acquire(key_name="my-lock", ttl=10)
lock.refresh()
print(f"Lock ttl: {lock.ttl()}")
print(f"Lock is alive: {lock.alive()}")
lock.release()
print(f"Lock is alive (after release): {lock.alive()}")

client.kvlock.acquire(key_name="another/lock", ttl=10)
lock = list(client.kvlock.list())[0]
lock.release()

# Lease & KV
lease = client.lease.grant(ttl=5)
client.kv.new(key_name="expiring-key", value="expiring-value", lease=lease)
print(f"KV items: {list(client.kv.items())}")
client.kv.new(key_name="my-key", value="my-value")
print(f"KV items: {list(client.kv.items())}")
time.sleep(6)
print(f"KV items (after expire): {list(client.kv.items())}")
