Question

I have used a dictionary to allow a user to input something, but the next problem is using a second word as a parameter for the called function. At the moment, I have:

def moveSouth():
    Player.makeMove("south")
def moveNorth():
    Player.makeMove("north")
def moveEast():
    Player.makeMove("east")
def moveWest():
    Player.makeMove("west")

function_dict = {'move south':moveSouth, 'wait':wait, 'sleep':sleep,
                 'move north':moveNorth, 'move':move, 'look':look,
                 'move east':moveEast,
                 'move west':moveWest}

And to get the input:

command = input("> ")
command = command.lower()
try:
   function_dict[command]()
except KeyError:
   i = random.randint(0,3)
   print(responses[i])

However, rather than having to have 4 different functions to make a move, I was hoping there would be a way so that when the user inputs “move south”, it uses the first word to call the function, and then ‘south’ as a parameter for the direction in that function.

Answer 1

split() the input and then pass each part in separately.

command = input("> ")
user_input = command.lower().split()
command = user_input[0]
if len(user_input) > 1:
    parameter = user_input[1]
    function_dict[command](parameter)
else:
    function_dict[command]()
