"Lost in the Woods" text-based game
Your code is indented well, and appears to have no problems in this way.



When you start the game, you should have all code that would otherwise just run defined in a method like this:

if __name__ == "__main__":
    start()


You can learn about this more here: What does if __name__ == “__main__”: do?



It is very good that your main delegates all the work of starting a game to a start() method.



You should probably run your text through a spell checker, should this be "nobody", "civilization", "Burger King" (capitalized as a proper noun), and "sweat"?


  "No bobdy comes for you."
  "You see civiliztion and stop at the first buger king."
  "You sweet to death and die!"


There are many other misspellings in here.



I would probably create a method to print the options the user has, and you can pass the options as a tuple:

def print_options(options):
    for i in range(0, len(options)):
        print str(i + 1) + ". " + options[i]


This can now be called like this:

print_options(("t1", "t2", "t3"))




Your game will be a little boring once the user has played it a couple times.  There seems to be no element of randomness, so there is only one path to victory.  The user won't want to lose, so once they realize this, they probably won't play your game.  To defeat this problem, you should probably use a random number generator to randomly choose options, which can be weighted to give certain actions a higher probability of happening.



In start(), you recursively call start() if the user chooses to stay still.  In this case, it probably is not a big deal because you don't create a bunch of variables and the user won't choose to stay still forever, but it isn't always a good idea to do this because the call will be added to the stack recursively until the stack overflows (if this point is ever reached); instead, you should use a loop to display the prompt until the user chooses to move.



Your win() and dead() methods are essentially the same.  You should combine these into one method for ending the game.



When you open and read the note at cabin 2, I would not put that in a file by itself.  It does not describe what the program is doing any more than just printing the note with print - in fact, I think print shows what is happening better.  What it is doing is describing what the user is doing, which is very different than what the program itself is doing.
