Learn Python The Hard way 36 code efficiency - python

Hello I'm studying the book "Learn Python The Hard Way" by Zed Shaw and I have reached exercise 36 where we right our own game from scratch using loops and if statements.
My game is finished and it's running however the code itself looks so messy and inefficient. The main problem is with trying to get the user's choice and having to rewrite the same code for the same word but with a capital letter, example:
def puzzle1():
print "\"A cat had three kittens: January,March and May. What was the mother's name.\""
choice = raw_input("Mother's name?: ")
if "What" in choice:
print "You are correct, the door opens."
door2()
elif "what" in choice:
print "You are correct, the door opens."
door2()
elif "WHAT" in choice:
print "You are correct, the door opens."
door2()
elif "mother" in choice:
print "Haha funny... but wrong."
puzzle1()
else:
print "You are not correct, try again."
puzzle1()
I wonder if there is a way to have all these choices in one line, also if there is anything else I can make more efficient please let me know. Sorry for the silly question I'm new to programming.

Use str.lower and remove the multiple if/elif's for what.
choice = raw_input("Mother's name?: ").lower()
if "what" in choice:
print "You are correct, the door opens."
door2()
elif "mother" in choice:
print "Haha funny... but wrong."
puzzle1()
else:
print "You are not correct, try again."
puzzle1()
I would also loop instead of repeatedly calling puzzle1, something like:
while True:
choice = raw_input("Mother's name?: ").lower()
if "what" in choice:
print "You are correct, the door opens."
return door2()
elif "mother" in choice:
print "Haha funny... but wrong."
else:
print "You are not correct, try again."

I'm making a text based adventuere game in python and trying to add a third option but it's not working

I'm trying to make a simple text adventure game with three choices. But I can't seem to figure out why this isn't working.
This is the code I have been working on:
#Text based medieval adventure game
#Imported libraries are required

print ()
def choosePath(lower,middle,upper):
#This functions allows you to choose between multiple options
path = 0
while path < lower or path > upper:
number = input("What path will you take(" + str(lower) + " - " + str(upper) + ")?: ")

print ("Suddenly a man with a giant axe appears before you and slices you head off in a clean swoop\n")
else chosenPath == 3:

print ("You're close to the exit when suddenly a guard notices you")
print("He's about to call for back up when you dash right into his chest with your sword, leaving it in him and running out the campsite")
print("You make it to a safe forest and decide to rest\n")
displayWelcome()

else:
The other error is that nothing ever happens on initialization of choice because you forgot to input the "lower, middle, upper" values.

Python Maze Game trouble

I'm trying to make a game where you go through a maze and try to escape from a voice, but everytime the player says the wrong answer to one of the questions it says "Game Over" but then carries on where it kept off, I've tried a lot of things and researched, but I can't seem to figure it out, I'm only a beginner
`
import time
import os
print ("Your adventure starts as a young boy, running away from home becuase you're a rebel")
time.sleep(2)
print ("You find the famous labyrinth, do you go in?")
time.sleep(2)
answer = input("Make your choice, Yes OR No")
time.sleep(2)
print ("The answer",answer ,"got you stuck in a hole")
time.sleep(2)
print ("But you find a secret passage")
answer = input("Do you go through the door, Yes or No?")
if answer == "No":
time.sleep(2)
print ("Game Over.")
elif answer == "Yes":
time.sleep(2)
print("You hear a strange voice")
time.sleep(2)
answer = input("What do you say to the Voice, Hello or Who are you?")
if answer == "Hello":
print ("Hello")
elif answer == "Who are you?":
print ("Im your worst nightmare")
time.sleep(2)
print("You try and escape the labyrinth and turn a large gate with a gnome on the over end")
answer = input("Do you open the gate, Yes Or No?")
if answer == "Yes":
time.sleep(3)
print ("Game Over, you get brutally killed by a gnome, good job")
os._exit(0)
elif answer == "No":
time.sleep(3)
print ("You go the other way and see a light at the end of the tunnel")
answer = input("You see your family outside crying and waiting for you, do you go with them?")
if answer == "Yes":
print("You have a nice ending and you're sorry you ran away")
print("You have been graded: ")
elif answer == "No":
print("God smites you for being stupid.")
os._exit(0)`
take this block, for example
print ("But you find a secret passage")
answer = input("Do you go through the door, Yes or No?")
if answer == "No":
time.sleep(2)
print ("Game Over.")
elif answer == "Yes":
time.sleep(2)
print("You hear a strange voice")
time.sleep(2)
# continuation
if the user enters "No" it will print "Game Over" - which I assume is correct. However, control flow in the program continues past the if/else block. What you need to do is exit the program using something like sys.exit() or make sure your control flow only has paths forward if it should i.e. wrapping what happens next in the truthy part of the if/else block
if answer == "No":
time.sleep(2)
print ("Game Over.")
elif answer == "Yes":
time.sleep(2)
print("You hear a strange voice")
time.sleep(2)
# put continuation here

Building a mini text-based python game as homework of learn python the hard way

I'm new to this website so please bear with my questioning problems on the website. I need some help to finish off this mini text-based game as homeowork of learning python the hard way book. This is the code I wrote. and I don't know the missing links and what I've done wrong. Help would be appreciated!

Ok, I've fixed it. Your code has several indentation mistakes, Python requires four spaces or one tab indentation after a def statement.
Another thing is, that you used else with a condition test (else choice == "another room":). That is wrong, it should be elif choice == "another room": or just else.
You also may have noticed, that I changed raw_input() to input(). This converts all inputs to strings (input() will interpret intergers as integers, lists as lists and so on...), and is also more secure.
The last thing is, you run your program (start()) before definign all called functions, this cannot work!
Your code (fixed):
from sys import exit
def start():
print("You are in an old temple.")
print("There is a door to your right and left or you can walk forwad.")
print("Which one do you take?")
choice = input("> ")
if choice == "left":
gold_room()
elif choice == "right":
trap_room()
elif choice == "forward":
monster_room()
else:
dead("you got caught by the ancient gods and you must be killed.")
def monster_room():
print("you're in a room with a monster. what you gonna do?")
choice = input("> ")
if "left" in choice:
print("you are going to the gold room")
gold_room()
elif "right" in choice:
print("you are going to the trap room")
trap_room()
else:
dead("couldn't understand what did you say so you are dead!")
def gold_room():
print("you chose the left room. now you are in a room with a pot of gold!")
print("you can take the pot.")
print("or you can just rob the money in it.")
print("or you go go to other rooms.")
choice = input("> ")
if choice == "take the pot":
print("you are a millionaire from now on!!!")
elif choice == "rob the money":
dead("you will never rest in piece!")
elif choice == "another room":
monster_room()
def trap_room():
print("you are now in a trap room.")
print("there is a hidden trap in this room.")
print("be careful!")
print("you can go back to the monster room")
print("or you can find the trap")
choice = input("> ")
if "find" in choice:
start()
elif "back" in choice:
gold_room()
def dead(why):
print(why, "rekt!")
exit(0)
start()
I would call the start() function at the end, after all the functions you defined. A usual way to write that is to write the following code at the end:
if __name__ == "__main__":
start()
This basically means that the programm runs the start() function at the end, if you're executing the file.
Furthermore you have to leave spaces after defining a function. You wrote:
def monster_room():
print "you're in a room with a monster. what you gonna do?"
but it should be:
def monster_room():
print "you're in a room with a monster. what you gonna do?"
If that didnt help, specify the problem

Learn python the hard way - exercise 36 function problems

I'm learning to code through learn python the hard way, and I've recently gotten stuck for the first time. For this exercise we're supposed to write our own game. I did so, but for some reason whenever I run it the right_room() function exits after I put in an answer, instead of proceeding to the next room. Any help would be greatly appreciated. Here's my code:
from sys import exit
def bear_room():
print "You are in a room with a bear."
print "You have two choices. left or right?"
next = raw_input("> ")
if next == "left":
left_room()
elif next == "right":
right_room()
else:
print "No idea what that means..."
def left_room():
print "You went left."
print "There are two doors. right or straight"
next = raw_input("> ")
if next == "right":
bear_room()
elif next == "straight":
second_left()
else:
print "What are you saying, bro?"
def second_left():
print "You went straight."
print "You again have two choices. straight or right?"
next = raw_input("> ")
if next == "straight":
print "You won! Congrats."
exit(0)
elif next == "right":
dead("You opened the door and walked off a cliff. Goodbye!")
else:
print "I didn't quite catch that."
def right_room():
print "You went right."
print "There are two doors. straight or right?"
next == raw_input("> ")
if next == "right":
dead("Oops, a tiger just ate you")
elif next == "straight":
second_right()
else:
"What?!?!?!"
def second_right():
print "You went straight"
print "Nice choice."
print "You have two choices: left or straight"
next == raw_input("> ")
if next == "left":
dead("You just fell 1 million feet to your death.")
elif next == "straight":
print "You made it out alive!"
exit(0)
else:
"WTF?"
def dead(reason):
print reason, "good job!"
exit(0)
def start():
print "You are about to enter a room."
bear_room()
start()
It looks like you're trying to assign to the next variable, but you used the equality check operator (==).

Variable values

I have this mini-text game for a tutorial on python and I'm using the fourthdoor/vault function to ask the player the code and if entered correctly it changes the value of a variable to be used as a key to open the third door. The problem is even if the value of the variable is changed when the vault code is given correctly, I still can't open the door.
Can anyone help me?
When python encounters haskey = int(1) inside of vault, it creates a new local variable called haskey that you can only see inside of vault. You need to tell python that when it sees haskey in that function, you mean the global haskey that you declare at the top of the file. You can do this by adding global haskey to the beginning of vault. ie:
def vault():
global haskey
while True:
print "There is a security code for this door. Enter code:"
code = raw_input("> ")
