How to do it...

Let us create a few try-except code blocks and put one potential error type in each block. In order to get a user input, the argparse module can be used. This module is more powerful than simply parsing command-line arguments using sys.argv. In the try-except blocks, put typical socket operations, for example, create a socket object, connect to a server, send data, and wait for a reply.

The following recipe illustrates the concepts in a few lines of code.

Listing 1.7 shows socket_errors as follows:

#!/usr/bin/env python # This program is optimized for Python 2.7.12 and Python 3.5.2. # It may run on any other version with/without modifications. import sys import socket import argparse def main(): # setup argument parsing parser ...
