Hi, I am having trouble running nosetests in ex47 but I can’t figure out how to solve the problem. I went into the ex47 folder and double-checked all of my code and files. When I run nosetests, this error showed up:
TypeError: go() takes 1 positional argument but 2 were given
Here is the test code and the game code:
Game code:
class Room(object):
def __init__(self, name, description):
self.name = name
self.description = description
self.paths = {}
def go(self):
return self.paths.get(direction, None)
def add_paths(self, paths):
self.paths.update(paths)}
Test code:
from nose.tools import *
from ex47.game import Room
def test_room():
gold = Room("GoldRoom",
"""This room has gold in it you can grab. There's a
door to the north.""")
assert_equal(gold.name, "GoldRoom")
assert_equal(gold.paths, {})
def test_room_paths():
center = Room("Center", "Test room in the center.")
north = Room("North", "Test room in the north.")
south = Room("South", "Test room in the south.")
center.add_paths({'north': north, 'south': south})
assert_equal(center.go('north'), north)
assert_equal(center.go('south'), south)
def test_map():
start = Room("Start", "You can go west and down a hole.")
west = Room("Trees", "There are trees here, you can go east.")
down = Room("Dungeon", "It's dark down here, you can go up.")
start.add_paths({'west': west, 'down': down})
west.add_paths({'east': start})
down.add_paths({'up': start})
assert_equal(start.go('west'), west)
assert_equal(start.go('west').go('east'), start)
assert_equal(start.go('down').go('up'), start)
