- How to handle named arguments in a function
A command line interpreter (cmd) for python is a shell that basically performs Read, Evaluate, Print and Loop (REPL) through-out its operation. It allows commands from the user and then executes them The cmd module builds custom shells for a user to work with a program
Below is an example from Python Documenation site
import cmd, sys
from turtle import *
class TurtleShell(cmd.Cmd):
intro = 'Welcome to the turtle shell. Type help or ? to list commands.\n'
prompt = '(turtle) '
file = None
# ----- basic turtle commands -----
def do_forward(self, arg):
'Move the turtle forward by the specified distance: FORWARD 10'
forward(*parse(arg))
def do_right(self, arg):
'Turn turtle right by given number of degrees: RIGHT 20'
right(*parse(arg))
def do_left(self, arg):
'Turn turtle left by given number of degrees: LEFT 90'
left(*parse(arg))
def do_goto(self, arg):
'Move turtle to an absolute position with changing orientation. GOTO 100 200'
goto(*parse(arg))
def do_home(self, arg):
'Return turtle to the home position: HOME'
home()
def do_bye(self, arg):
'Stop recording, close the turtle window, and exit: BYE'
print('Thank you for using Turtle')
self.close()
bye()
return True
if __name__ == '__main__':
TurtleShell().cmdloop()
