switch example with partial

from functools import partial


def update_pos(self, room, exit_name):
    # this ensures the pointer variables always
    # stays up to date to where the worm is currently at.
    self.curX, self.curY = self.worm_has_mapped[room][0], self.worm_has_mapped[room][1]

    # now we have to actually move the pointer
    # variables depending on which 'exit' it found

    def _update_pos(x=0, y=0):
        return self.curX + x, self.curY + y

    # define the different cases
    switch = {
        'east': partial(_update_pos, y=1),
        'west': partial(_update_pos, y=-1),
        'north': partial(_update_pos, x=-1),
        'south': partial(_update_pos, x=1),
        'northwest': partial(_update_pos, x=-1, y=-1),
        'northeast': partial(_update_pos, x=-1, y=1),
        'southwest': partial(_update_pos, x=1, y=-1),
        'southeast': partial(_update_pos, x=1, y=1),
    }

    update_pos_func = switch.get(exit_name)  # get the right case
    self.curX, self.curY = update_pos_func() if update_pos_func else self.curX, self.curY  # update position
