    ' Start a shell, with the given local variables. It prints the given
  banner as a welcome message.' 
    def IPythonShell(namespace, banner) :

        ipshell.mainloop (banner = banner) 
def PythonShell(namespace, banner) : 
        import readline, rlcompleter, code 
        readline.parse_and_bind ('tab: complete') 
        readline.set_completer (rlcompleter.Completer (namespace).complete) 
        code.interact (local = namespace, banner = banner)
