Python has lots of surprises for it's lovers, one such pleasant one is the cmd.Cmd module .    A programmer might encounter tons of project where she might have to write a command line interpreter for his program to execute it. Typical undergrad lab. projects have tonnes of such project where one has to implement something, say for example Graph or a toy ticket reservation system. All these projects require the developer to create a command terminal which will prompt the user to write a command from some predefined set of them and then print the result in the terminal. Python provides a brilliant solution to such repreatative task in the form of a module cmd.Cmd. The best part is that the it gives the developer the freedom to do his implementation task independently to the command interpreter module.

The great thing about TCP jokes is that you always get them. The problem with TCP jokes is that people keep retelling them slower until you get them. I would tell some UDP jokes too but I ne...
