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?
