How to update variable in if else statement with reference error

Question

Working on a textbase game where you can move your character through rooms however, I keep running into an error about my position variable not being referenced

current_position = rooms[0]
def player_moves_south():
    if current_position == rooms[0]:
        current_position = rooms[1]
        print('welcome too the Bedroom you can now move North or East')
        player_choice = input()
        return player_choice

        return current_position
    else:
        print('error')

I keep getting an error saying

'current_position' not referenced

Can anyone help? It will be much appreciated

Answer 1

When I tried it like this.

def player_moves_south():
     current_position = rooms[0]
     if current_position == rooms[0]:
        print('welcome too the Bedroom you can now move North or East')
        player_choice = input()

        return player_choice

        return current_position

     else:
         print('error')

player_moves_south()

It worked. I put the current_position in the function and it is giving me no error.

If you want to use the current_position variable outside the function you can global it in the function. Like this

global current_position
current_position = rooms[0]
