Python Text Adventure Boolean issue

[4lph40mega]

I cannot seem to figure out why my Boolean values will not change after going straight. I just decided to start coding less than aweek ago. Can someone help me figure out why these values will not change?```

def left():
    print("you hit a dead end. Do you want to go back?")


def right():
    print('You are encountered by a giant spider. Do you want to fight it?')


def straight():
    print('You find a chess with a sword inside of it. Do you want to take it?')



start_game = input('Type [Start] to begin or [Quit] to end:')

user_has_sword = False
sword_in_chess = True


while start_game.lower() == 'start':
    direction = input("""   
You find yourself in a dark room with three ways to go. 
Which way do you want to go? [Left, Right, Straight]""")

    if direction.lower() == "left":
        print("you hit a dead end. Do you want to go back?")
        answer = input('> ')
        if answer == 'yes':
            continue
        else:
            print('You bring shame')
            break

    elif direction.lower() == 'right':
        print(right())
        answer = input('> ')
        if answer == "yes" and user_has_sword == True:
            print('You won!')
            break
        elif answer == 'yes'and user_has_sword != True:
            print('You died')
            break
        else:
            print('You go back to the main room')
            continue

    elif direction.lower() == 'straight':
        print(straight())
        take_sword = input('> ')
        if take_sword == 'yes':
            user_has_sword = True,
            sword_in_chess = False
            print('The sword has been added to your inventory and you go back.')
            continue
        elif user_has_sword is True and sword_in_chess is False:
            print('You already have this item')
            continue

        else:
            print('You go back')
            continue

    elif answer != 'left' or 'right' or 'straight':
        print('Invalid option')

else:
    print('Bye!')

I think you have a logical error. You are setting

user_has_sword = True,
sword_in_chess = False

in

elif direction.lower() == 'straight':

everytime the user enters 'yes' to picking up the sword.

You can add another conditional statement either after or before to check if the sword has already been picked up and or is not in the chess anymore

if take_sword == 'yes':

One way the logic could like like the following:

...
elif direction.lower() == 'straight':
        print(straight())
        take_sword = input('> ')
        if take_sword == 'yes':
         if user_has_sword is False and sword_in_chess is
         True:
           user_has_sword = True,
           sword_in_chess = False
           print('The sword has been added to 
           your inventory and you go back.')
           continue
         elif user_has_sword is True and 
         sword_in_chess is False:
            print('You already have this item')
            continue
    ...

Let me know if this is this unclear and I can try to clarify.

That did it. Can you explain why it needed a nested if statement?

[avan]

@4lph40mega Sure.

let's put it in pseudo code.

if direction is straight
 print straight message e.g. "Do you want to pick up sword?"
 if user DOES NOT have sword and sword IS in chess
  user has sword now & 
  remove sword from chess
 else if user HAS sword and sword IS NOT in chess
  print "You have already picked up sword"
 end nested if
end first if
 

All we are doing is making sure that user does not have the sword before we change
user_has_sword = True,
sword_in_chess = False
Otherwise we don't do anything except print "You have already picked up sword"

Keep in mind the solution above is probably not the most optimal solution.
One way you can improve it is by changing the second nested conditional statement from

elif user_has_sword is True and 
         sword_in_chess is False:

to just

else: 

Another way to improve is to check if the sword is in the chess before you you ask if they want to pick up the sword. But that has more to do with how you want to design the game and not necessarily if the code is correct.

Hope this helps. Do you mind selecting my answer as the correct answer if it worked for you? Thank you!
