To elaborate on IVA's answer: embedding-a-shell, incoporating code and Ipython.

def prompt(vars=None, message="welcome to the shell" ):
    #prompt_message = "Welcome!  Useful: G is the graph, DB, C"
    prompt_message = message
    try:
        from IPython.Shell import IPShellEmbed
        ipshell = IPShellEmbed(argv=[''],banner=prompt_message,exit_msg="Goodbye")
        return  ipshell
    except ImportError:
        if vars is None:  vars=globals()
        import code
        import rlcompleter
        import readline
        readline.parse_and_bind("tab: complete")
        # calling this with globals ensures we can see the environment
        print prompt_message
        shell = code.InteractiveConsole(vars)
        return shell.interact

p = prompt()
p()
