Struggling with nested list

[gr3yali3n]

Now I’ve gotten a slight grasp on dictionaries ,the join() and split I am working on understanding nested list and how to process them at least I think that that is my problem at this point here is the code I’m playing around with It’s supposed to print location and a list of directions then ask for input as to which direction do you want to go but I get stuck with it repeating the same location never changing.
I got it going once by correcting an error in exits but when I typed it out again I get the same
Error.

location={
	0:'you are at home',
	1:'you are on a road' ,
  2:'you are on a hillside',
  3:'you are looking at a lake',
  4:'you are in the country' ,
  5:'you are in outer space! ' }

exits=[
{'q':0},
{'w':2,'e':3,'n':5,'s':4,'q':0},
{'n':5,'e':1,'q':0},
{'w':1,'q':0},
{'n':1,'w':2,'q':0},
{'w':2,'s':1}]

loc=1
while True:
	avail_exits=','.join(exits[loc].keys())
	print(location[loc])
	if loc == 0:
		break
	direction=input('what direction do you want to go in?' + avail_exits)
	if direction in exits[loc]:
		loc == exits[loc][direction]
	else:
		print('you cannot go in that direction')
