Question about files?
I want to create a program where a user can type what ever they want to, have it saved to a file, and the be able to re-open it and read it. How would I do this? Thanks! -- http://mail.python.org/mailman/listinfo/python-list

No, what I mean is for the user to input text directly into the python
program, then the program would save it to a file and display it after
it is created.

text adventure game problem
okay, I'm having this one problem with a text adventure game. It's
kind of hard to explain, but I'll do my best.
[code]
def prompt_kitchen():
global gold
gold_taken = False
while True:
prompt_kit = raw_input('>')
if prompt_kit == 'examine cabinet 1' and not gold_taken:
print '''This cabinet has a lot of cups in it with all
different
designs and shapes. Where are the people anyway? How come there's
nobody here?
In one of the cups you find 8 gold.'''
gold = gold+8
gold_taken = True
pass4()
elif prompt_kit == 'examine cabinet 1' and gold_taken:
print \
'''This cabinet has a lot of cups in it with all
different
designs and shapes. Where are the people anyway? How come there's
nobody here?'''
pass4()
def pass4():
global gold
print 'You have', gold, 'gold'
pass
[/code]
Okay, now for my problem.
In the above function, there's the option to examine a cabinet and get
8 gold. (everyone here knows that...but I'm just trying to state my
problem...)
Unfortunately, it kind of doesn't work.
After the first time I 'examine cabinet 1' in my game, I get 8 gold
and I can't get it again.
But, If I leave the room and come back to it, then it's as if I had
never gotten the gold the first time, and I can get it again.
How do I fix this?

Here's a sample code that, in fact, does work. In this code, when run,
I can only get the gold once.
def prompt_house():
global gold
gold_taken = False
while True:
prompt_hou = raw_input('>')
if prompt_hou == 'examine table' and not gold_taken:
print \
'''There are a lot of car magazines here.
You flip through them and find 5 gold.
'''
gold = gold+5
gold_taken = True
elif prompt_hou == 'go west':
# this gets you out of the loop
go_west()
# more elif choices here ...
elif prompt_hou == 'examine table' and gold_taken:
print '''There are a lot of car magazines here.'''
go_west()
def go_west():
# just a dummy funk
global gold
print gold
pass
# test
gold = 0
prompt_house()
But what's the difference between this and the one that I posted?

I can't even compile your code to see how it works, Dennis. I'm
confused about what that does.
