How can I leverage Python s Scapy library for network packet manipulation in ethical hacking

I’m exploring network packet manipulation for ethical hacking purposes, and I’ve heard that Python’s Scapy library is powerful for tasks like sniffing, spoofing, and injecting packets. However, I’m new to Scapy and not sure how to use it for common network tasks like crafting custom packets or simulating attacks such as ARP spoofing.

Can someone provide a basic example of how Scapy can be used for packet sniffing and manipulation? Additionally, any tips on using Scapy safely for testing in a controlled environment would be appreciated.
