How can I perform a ping or traceroute using native python?

Question

ICMP Ping is standard as part of the ICMP protocol.

Traceroute uses features of ICMP and IP to determine a path via Time To Live values. Using TTL values, you can do traceroutes in a variety of protocols as long as IP/ICMP work because it is the ICMP TTL EXceeded messages that tell you about the hop in the path.

If you attempt to access a port where no listener is available, by ICMP protocol rules, the host is supposed to send an ICMP Port Unreachable message.
