Python (linux) Text based game input error

I have been working on a text-based adventure game. I've revised it a few times and can't seem to get the outcome I want, when I attempt to create EVENTS rather than simply relying on an abundance of PRINT strings. Whenever I choose the option I want (door 1 in this case), then the following options, the input is unresponsive or gives me an error. Below is a portion of the code for door 1. A little clarity would be appreciated!
def main():
import sys
from colorama import init
init()
init(autoreset=True)
from colorama import Fore, Back, Style
def run_event(event):
text, choices = event
text_lines = text.split("\n")
for line in text_lines:
print(Style.BRIGHT + line)
print()
choices = choices.strip()
choices_lines = choices.split("\n")
for num, line in enumerate(choices_lines):
print(Fore.GREEN + Style.BRIGHT + str(num + 1) + ". " + line)
print()
return colored_input()
def colored_input():
return input(Fore.YELLOW + Style.BRIGHT + "> ")
print ("")
print ("")
print (" WELCOME TO THE MAZE ")
print ("")
print ("")
print ("You have found yourself stuck within a dark room, inside this room are 5 doors.. Your only way out..")
print ("")
print ("Do you want to enter door 1,2,3,4, or 5?")
print ("")
EVENT_DOOR1 = ("""

what do you want to do?
""","""

""")
EVENT_ALIEN = ("""

EVENT_ALIEN2 = ("""

""")
door = colored_input()
if door == "1":
run_event(EVENT_DOOR1)
alien = colored_input()
if alien == "1":
run_event(EVENT_ALIEN)
elif alien == "2":
run_event(EVENT_ALIEN2)
restart=input("Start over? Yes or No? ").lower()
if restart == "yes":
sys.stderr.write("\x1b[2J\x1b[H")
main()
else:
exit()
main()

You run_event function unnecessarily makes another call to colored_input() when it returns, causing the unresponsiveness as the script waits for another input. Remove the return colored_input() line and your code would work.
Also note that you should add a comma to the single-item tuple assigned to EVENT_ALIEN2; otherwise it would be evaluated as a string:
EVENT_ALIEN2 = ("""
You catch the alien off-guard. He stumbled and hisses in your direction. You scream in terror before he grabs the knife, and punctures your throat as he rips off your limbs.")
You died.. GAME OVER.. Mistakes can't be made this soon.. OUCH

python global name not defined after transition to classes

I've found a few versions of this question on the site, but none of the answers quite give me an answer I understand (this question is the closest, but the 'already answered' answer seemed to go off in a different direction).
I'm working my way through the learn python the hard way book and have gotten to the point where I'm trying to build a simple combat system for a game. The good news is that it seems to work when I leave it as a stand alone program. The bad news is that it breaks as soon as I try and add it as a class. I can add the full code if it is helpful, but I think the question is essentially related to code that looks like this:
class Room1(Scene):
def kick():
#things happen here
def start():
move = raw_input("> ")
if move == "kick":
kick()
start()
This worked fine when it was just a standalone set of defs, but now that I've added classes it throws up a global name error when move == kick. What am I missing?
Thanks in advance, sorry if there is an obvious answer that I'm missing.
Thanks to everyone for the quick responses! It looks like it may be helpful for me to add the entire code. Just to be clear, this is part of a larger game modeled on example 43 from Learn Python the Hard Way. I very much appreciate the suggestions on improving the structure, but my sense right now is that I want to figure out why this doesn't work with the structure I almost understand before moving on to change more things. Of course, I'm more than willing to accept an answer of "what you are trying to do does not fit in the structure you are trying to use."
When I run the code below as part of a larger structure (in the interest of space I won't paste the entire thing, but the game engine structure is linked to above) I get the error I described. I tried adding 'self.start()' or 'Room1.start()' I get errors that name 'self' or name 'Room1' is not defined.
class Room1(Scene):
gothon_power = 500
move_points = 10

def kick(self):

move_points = move_points - 2

print "The Gothon is down to %s health points." % gothon_power
print "You are down to %s move points." % move_points
print "\n"
print "What's your next move?"
move = raw_input("> ")

print "\n"

elif gothon_power < 1 and move_points > 0:
print "Congratuations, you killed the Gothon!"
return 'room2'
else:
print "The Gothon still has health but you don't have moves."
print "You know what that means."
print "\n"
print "The Gothon killed you."
return 'death'
def start(self):
print "It is time to fight the Gothon"
print "First, let's pause to explain the fighting rules."
print "\n"
print "The Gothon has 500 health points."
print "You have 10 move points."
print "\n"
print "Kicks cost 2 move points and do between 10 and 200 points of damage."
print "Punches cost 1 move opint and do between 1 and 100 points of damage."
print "\n"

print "moves out of health points you lose."
print "\n"

move = raw_input("> ")
if move == "kick":
kick()
elif move == "punch":
punch()
else:
print "This isn't going to go anywhere unless you type 'kick' or 'punch'"
start()
start()

A proper set of methods on a class will look like:
class Room1(Scene):
def kick(self):
#things happen here
def start(self):
move = raw_input("> ")
if move == "kick":
self.kick()
Room1().start()
But you might want to rethink your design a little bit. It really doesn't make sense for a Scene to query for input. You'll have to replicate that code in every room in your game.
Think about this kind of top-level driver for a minute:
game = Game()
starting_room = FrontPorch()
game.move_to(starting_room)
while not game.is_over():
move = raw_input("> ")
cmd, args = move.split(None, 1)
game.current_room.do_command(cmd, args)
Then let each room process the commands that it does specially. At the base level Room class, you can implement commands that are common to most rooms, like "GOTO", "LOOK", "WHERE", etc. Then rooms that allow kicking would override do_command and include logic like you have now.
Here is a presentation I gave at PyCon '06 on writing a text adventure. Skip over the parsing stuff, and go to the part where the game/room/items design is described. You don't have to follow this design verbatim, but you might get some ideas about how your objects and classes will interact. Think about that before actually diving in to write a lot of code.

You can't execute instance methods of a class, without creating an instance. For example, you could instead write:
class Room1(Scene):
def kick(self):
#things happen here
def start(self):
move = raw_input("> ")
if move == "kick":
self.kick()
room = Room1()
room.start()
However, I don't recommend using a class at all in this case. Classes are meant to give a way to represent your own custom objects with state. For example, you could have a Monster class with attributes damage, name, etc.
For this example that you show, it's probably better to just use a function for Room1.

To call kick() as a method you need to use the self.<method Name> syntax and add self as the first argument to it:
def kick(self):
#things happen here
print('kicking')
#call method
self.kick()
or additionally make kick() a static method by calling simply
A.kick()

Python pass on from a class

I'm trying to pass on the value of elf_rescued from the class InterrogationRoom to the class Armory. If the elf is rescued then I would like the user to be able to open the weapon locker, however if he isn't then the locker should remain untouched (as he won't tell you about your gear then). I get more confused with each attempt. Can anyone give me a hint on what I'm doing wrong, please?
The error I am getting with this method is:
You enter the armory, where you see a weapons locker and 3 orcs in the back of the room.

Before all classes, define elf_rescued as a global variable:
elf_rescued= False
Then, in each method you use elf_rescued declare
global elf_rescued
before making any use of it, especially assignment.
I don't understand what you want to do with method situation_change. You probably just need to set elf_rescued= True and get rid of this method.

I think this is the result of an indentation error. In your posted code, you have
class Game(object):
def __init__(self, start):

print "time. You won!"
exit(0)
a_game = Game("central_corridor")
a_game.play()
So that you're defining a_game inside the Game class, when Game isn't defined yet. Shift it to the left to move it outside the Game scope, i.e.
a_game = Game("central_corridor")
a_game.play()
(on the same level as class Game(object):).

Learn Python the Hard Way ex41 Extra Credit

working my way through LPTHW and am stuck on the extra credit for exercise 41:
Extra Credit:
Add cheat codes to the game so you can get past the more difficult
rooms.
Instead of having each function print itself, learn about “doc
string” style comments. Write the room description as doc comments,
and change the runner to print them.
Once you have doc comments as the room description, do you need to
have the function prompt even? Have the runner prompt the user, and
pass that in to each function. Your functions should just be
if-statements printing the result and returning the next room.
As I understand so far using docstrings like this is frowned upon, but here's what I've come up with:

Everything runs fine except for "return 'death'". It just exits after printing the following:
--------
None
In the runner function near the bottom, I thought adding the 'elif room == death:' bit would work as without it, it just hangs waiting for raw_input() and then prints a random 'quip' as it should after I press ENTER. Can someone help me understand what I'm missing? Any help appreciated!
EDIT
Thanks to some lighting quick feedback this is what I've got, though rocksportrocker's solution is simpler:
def runner(themap, start):
next = start
while True:
## Global variable in order to pass prompt value to rooms
global globvar
room = themap[next]
## Room dependent prompts
if room == laser_weapon_armory:
print "\n--------"
print room.__doc__
prompt = raw_input("[keypad]> ")
elif room == escape_pod:
print "\n--------"
print room.__doc__
prompt = raw_input("[pod #]> ")
elif room == the_bridge:
print "\n--------"
print room.__doc__
prompt = raw_input("> ")
elif room == central_corridor:
print "\n--------"
print room.__doc__
prompt = raw_input("> ")
else:
pass
## Set raw_input from prompt to Global variable (globvar)
globvar = prompt
next = room()

death has no doc string. if room==death then print room.__doc__ prints None. in the following if/elifs you return from the function runnner which results in the programs end.
Your program will work if you add the missing doc string and if you replace return "death" in runner() by a simple "pass", or by ommitting the corresponding elif clause.
