Hello, I've been getting into python and reading a book to get used to it, but I'm having some trouble understanding a part about while loops.


 done = False
 
 while not(done):
 
 quit = input("Do you want to quit? ")
 
 if quit == "y":
 
 done = True;
 
 
 
 attack = input("Does your elf attach the dragon?")
 
 if attack == "y" :
 
 print ( " Bad choice , you died . " )
 
 done = True ;

Whenever I input anything into quit it just says that it wasn't defined, and when I try defining y like : y = "y" or something it doesn't actually quit. And this is straight from the book I am learning from.

And also, what books or tutorials would you recommend?

I'm not a python man, but I done a bit of reading around your problem. Look like Input() expects a python expression to be entered as input to be evaluated. I think the function you want to use for general input from a user is raw_input().

Input() : http://docs.python.org/library/functions.html#input
raw_input(): http://docs.python.org/library/functions.html#raw_input

I'd highly recommend this Web site for learning the basics of Python: http://www.learn-to-program.net/

Also, see my thread: http://www.gamedev.n...game-in-python/

Here's a simple while loop (ignore white space):

option = 0
 
 while option < 10:
 option = option + 1
 print "Inside the while statement until option is 10!"
 print "Option is set to: ", option
 raw_input()
 
 print "\nOutside the while statement!"
 print "Option is set to: ", option
 print "Press enter to end the program."
 raw_input()

Hope this helps!
