# 2. Dictionary (Key-Value Hash Map)
config = {"port": 8080, "ssl": True, "workers": 4}
 
# 3. Set (Unordered Unique Elements)
unique_ips = {"192.168.1.1", "10.0.0.1"}
 
# 4. Tuple (Ordered, Immutable)

# List Comprehension for inline filtering
active_servers = [s.upper() for s in servers if "db" in s]
